There's a good cam chart to follow by. To get deep into 11s with only a cam, you're going to have to past extreme. Probably something with a 240/240 cam, and that car will barely be streetable.

to answer your question 92trans, yes the will work with a lil massaging to hook it up to the fpr. im using the aeromotive one and am gonna replace all the lines and maybe go one size up because you do have a limit on power with the stock lines.

im also trying to do this swap on my 92 firebird 3.1L. many of the swapping info on this forum was related to 5.0's and 5.7L TBI's and TPI's, do i need to do anything different b/c of my engine?
the guy who started this forum said that your stock 3rd gen a/c compressor works fine and fits gd. so y wud u guys want to play around w/ the new compressors?
im not sure y u guys want to try to remodle the 3rd gens beutiful interior and put that shtty lookin 4th gen style in?
your just makin it hard on yourself. well i take that back since its a matter of oppinion but i think the 3d gen gages and interior look far supieor to the 4th gens.

Re: --- LS1 SWAP Question and Answer ---
Many people including myself want more information on the LS1 swap so I have compiled this information from many posts and hours of reading. Please help me out and add any info you can think of. Also if anything is incorrect feel free to correct me.
LS1 Advantages & features:
- All aluminum block, oil pan, and plastic intake manifold saves roughly 100-150 lb off the front end of the car.
- Sequential Fuel injection (good for gas mileage)
- DIS, 1 coil per cylinder
- Camaro\Firebird LS1’s are rated stock 305-335(depending on the year and model) Rear wheel HP!
- 6 bolt main
- 15 degree cylinder heads
Q: Will the LS1 fit under the stock hood?
A: Yes
Q: Are there any clearance issues with the LS1 engine?
A: Here are a few that may arise:
1) You may need to cut away at a frame cross brace bracket for clearance of the A/C compressor, as see here, or here.
2) The stock LS1 coils may hit the heater box. You can get around this by modifying the coil bracket or using the truck 6.0 LS1 coils.
3) You will have to notch the cross member if you would like to use the A/C that comes on the 98-2002 F-Body LS1’s (more info below)
Q: Are any parts interchangeable between the LS1 (Gen III SBC) and the Gen I and II (LT1) SBC?
A: No, the LS1 is a completely new engine design.
Q: Do you need special motor mounts?
A: Yes, You can buy the motor mounts, transmission cross member, and other LS1 swap products from the dealers links at the bottom of this post.
Q: Can you use the stock transmission cross member?
A: No, not without modifying it. Yes, You can buy the motor mounts, transmission cross member, and other LS1 swap products from the dealers links at the bottom of this post.
Q: Can you use your stock driveshaft with the LS1 manual T56 or 4L60E auto transmission?
A: Yes
Q: Can you use the stock driveshaft off a 98-2002 F-body LS1 manual T56 or 4L60E auto transmission car?
A: Yes
Q: Can you use your stock gauges?
A:
Speedometer:
- Electronically driven speedometer (90+ Camaro, 87+ Firebird)
Electronically driven speedometer can be reused on the LS1 swap. You will need to reprogram the LS1 computer so it will output the proper signal to the stock gauge cluster. Another option is to purchase a signal conversion box like the ones from the dealers links below to convert the signal outputted by the VSS (vehicle speed sensor) into the proper signal for the stock speedometer.
- Cable drive speedometer (pre 90 Camaro, pre 87 Firebird)
If you have a cable driven speedometer you can hook up a cable drive unit More info here OR you can buy a modified tail housing for your transmission from http://www.jagsthatrun.com/. This tail housing will give you the ability to use your stock cable drive speedometer.
Tach:
You can use the stock tach but it will be off slightly you will need to use a calibration box to make it fully accurate.
Temp gauge:
You can use the LS1 stock sender on the LS1 block.
You can also use the stock thirdgen temperature gauge sending sensor. This sender can be mounted on the driver or passenger side head on the LS1. You will need to drill and tap the hole to fit the stock bigger sending unit, as seen here.
http://www.montecarloss.com/ls1monte...s/TempInst.jpg
Fuel gauge:
This won’t be a problem; this is tied to your fuel sending unit.
Battery Volts gauge:
Also not a problem, tie up to the batter and has nothing to do with engine.
Oil pressure gauge:
anyone????
Q: Will I have to make my own fuel lines?
A: Yes, this can be done with AN hose and AN fittings. To convert your stock fuel line fitting (Fuel line from the fuel tank) to AN fittings you will need Earl's 9894DBH and 9894DBJ fuel fittings.
Also you will need a fuel pressure regulator which will give you the return line that the 98-2002 F-Body LS1 fuel rail does not have. Here is one that will work: Aeromotive A1000-6 P/N 13109
To connect this all to the LS1 fuel rail you will need to weld or braze an AN fitting on the fuel inlet on the LS1 fuel rail. Or you can buy the fittings from http://www.hotrodlane.cc/ to convert the stock LS1 fuel rail fitting to an AN fitting.
Another option is to use a fuel rail out of a 97 corvette. These rails have a return line on them, you will still need to modify the rail to accept AN fittings (or buy the conversion fittings as mentioned above).
Q: Will I need a new fuel pump?
A: You can use your stock TPI fuel pump but I don’t think it will last very long running at the stock LS1 58 PSI, I recommend a aftermarket high pressure pump. If you have a TBI or carbureted car you will have to buy a new high pressure pump. A good pump to get is the WALBRO GSS340M. You can get this pump with hot wire kit from http://www.racetronix.com/.
Q: What about the wiring harness?
A: You can use a stock LS1 wiring harness. Or you can buy one from painless wiring.
Q: Is there any chip programming software or hardware for the LS1?
A:
You can use LS1 Edit to reprogram the computer, http://www.carputing.com
Q: Can I use the stock LS1 computer?
A: Yes but you will have to get it reprogrammed or reprogram it yourself to disable things like VATS, fuel tank pressure sensor, rear O2 sensors.
Q: Can I use my stock thirdgen harness or computer?
A: No
Q: What to do about VATS?
A: You can disable VATS by reprogramming the computer. Also most aftermarket wire harnesses come with a VATS bypass box.
Q: Won’t the computer trough a code without the LS1 gas tank pressure sensor?
A: Yes, but you can disable this sensor by reprogramming the ECM using software like LS1Edit.
Q: Where do you mount the ECM?
A: Is the ECM watertight??? If so then it could be mounted under the hood. Does anyone know if it will fit in the factory position?
Q: Will the stock SBC Gen I or II headers bolt up to a LS1?
A: No, SBC Gen I and II has exhaust ports like this:
O OO O
And LS1 look like this:
O O O O
Q: Will the stock exhaust system bolt up?
A: No, you will need to fabricate your own exhaust system. The stock cast iron LS1 headers will fit but you will need to fabricate the piping from the headers to the muffler. Also you will have to create 4 O2 bungs in the exhaust to mount the 4 oxygen sensors the computer needs. You can reprogram the computer to eliminate the 2 after cat oxygen sensors or you can buy oxygen sensor simulators for the back to oxygen sensors.
Hawks Third Gen now sells custom long tube headers for LSx swaps also.
Q: What is the difference from a ls1 and ls6?
A: The LS6 has different heads and Cam (the 97-2000 LS1 has a different intake). 2001+ LS1 blocks use the LS6 intake.
Q: Has the LS1 block had any revisions?
A: Yes, GM have released a few new castings over the years. I believe the most recent casting is the 2000+ block. They have improved the oiling system in the newest casting.
Q: Can I use a LS1 out of a C5 corvette (Y-Body)?
A: Yes, you will need to do some more fabrication and time to make it work. First the corvette oil pan will not work; you will need to switch it with a 98-2002 F-Body pan. Also the corvette has drive-by-wire which means there is no throttle cable. You will have to rig up the throttle position sensor the corvettes use directly to the gas pedal.
Q: What car should I get my LS1 from for a swap?
A: Most people on this site use LS1 from a 98-2002 F-body so you will find the most information on this swap on this site. If you do decide to get a LS1 from an F-body the best years to look for is a 2001-2002 block. These blocks have the LS6 intake and a revised block design.
Q: Can you still have A/C with an LS1?
A: Yes, there are a few options.
1) I feel this is the easiest and lest time consuming option. You can buy the conversion brackets from the parts dealers listed at the bottom of this post. This will allow you mount your stock AC compressor to the LS1 pulley setup.
2) If you want to use the stock LS1 A/C compressor you need to cut away at the engine cross member and notch it as shown here Click here.
You will also need to you will have to fabricate your own AC Lines. Anyone know what type of pipe or hose you would use for this?
The corvette accessories may resolve this problem. As seen in the pictures in the post below you can see that the A/C compressor is in a higher location on the corvette accessories. It may work but I can’t say for sure since I have no way of knowing if it will work.
Q: Will the Lightweight LS1 raise the front end of my car?
A: Yes it will. The general number I tend to hear is about an inch.

Re: --- LS1 SWAP Question and Answer ---
The throttle cable must be changed over to a NON traction controlled ‘99 fourth gen LS1 cable. It fits nicely through the stock third gen hole although you will need to bend your stock third gen gas pedal arm outwards to take up the slack and use a large washer and some tie wraps to mount the grommet to the firewall as it is smaller than the stocker.

Re: --- LS1 SWAP Question and Answer ---
as a temperary solution you can use the stock cable by clamping it to the dip stick tube if your stuck

Re: --- LS1 SWAP Question and Answer ---
Sorry I should expand on that one a little more
Normally the cable sleeve is attached to the bracket close to the tb the stock one is way to short so by moving it back and connecting the cable sleeve to the dip stick tube and lenghten the cable long enough to attach to the tb will get it done on a temp basis

Re: --- LS1 SWAP Question and Answer ---
Do your self a favor and go to youngsfbody.com and purchase the wiring harness (1200.00) specificly made for this swap they also have the throdle cable @ 24.95 i think. unless you are very good at converting the existing harness into the cars wiring system this is the only way to go
The obd-2 would need to be the gm one with 4 wires coming off it and they must be in the right order
How far is the build so far?

i finally found an obd2 on ebay.
i just got the last of the parts in the mail that i need. i have the old 355 tpi pulled out. trying to sell it but nobody wants a cammed 355 i guess. and have all the wiring and dash out and engine bay is super clean now
entire dash is rewired just have to put dash back together and put new gauges in. now im working on putting the cam in the ls1 and putting the intake and top end on. by the end of the week the ls1 should be completely rebuilt. then i have to worry about the motor mounts which i have no idea what they mean by relocating them. so far alot of the stuff they say to use on here was wrong so now im waiting on the other set of motor mounts to come in

Re: --- LS1 SWAP Question and Answer ---
Sounds good so far, the motor mounts are best gotten from a supplier around a $100.00 which it sounds like thats what you are doing. So when you go to mount them you will find that two of the holes line up so you will need to drill out the other ones. One suggestion if you have a 01 or 02 LS1 then put a 1/8" shim under the lower half of the motor mounts. This will raise the motor up slightly to make it easier down the road if you intend to install the LS A/C system. The reason for raising it up is if you do not then when you install the A/C the steering arm may make contact. This may no matter if you changed out the K member to the tube one but it sounds like you kept the original one. As far as the obd2 you could go the any auto wrecker and get one.

Re: --- LS1 SWAP Question and Answer ---
Well you took on a big task is it a steel block or alum.? Just curious, my engine is out of a 02 trans am, that said is the A/C drive with a separate belt if so you just remove that belt and will have no affect the other accessoies. Some of the after market suppliers have kits that come with all parts required, so they say to make it work in this application.
What all did you change to make your eng fit pan,oil pump pick up what else? How much hp are you going for?

Re: --- LS1 SWAP Question and Answer ---
not sure where the a/c is mounted on your eng but if when it is sitting on the motor on the floor in the stock possition and is lower than the intake then it will fit. The f-body ls1 has the a/c mounted on the lower left looking at it from the front and to make it fit you need to cut out some of the k member in that location. I did all that and made it fit just to find out that the steering idler arm hit it when you turn the steering so I go with a/c no bigge for now. That was why I suggested raising the mounts up slightly.

Does anyone know of a by-pass hose that will work on the LS so that you dont have to run heater hoses?

Re: --- LS1 SWAP Question and Answer ---
No not nessessary the motor mounts that fit the ls1 will be required and if you are planning on using the A/C from the ls1 you will need to make sure the engine is mounted back a 1/2 inch from the existing holes in the support frame otherwise the A/C will not fit in (it will hit the steering arm) on the other hand if I had it to do over again I would put in all new front end then it becomes plug and play. on another note there is a A/C bracket on the market that suggests that you could mount the A/C from the old engine, by relocating it up top save your money it will not work I bought it and tried several ways to make it work and in the end riped it off and gave up.

Re: --- LS1 SWAP Question and Answer ---
I used a 00 Trans Am dash with a 97 cluster. The LT1s had analog guages, so you can use the 3rd gen's C100 wiring to feed the gauges. Since you're doing the LS1 & pcm, you can use the newer gauges, you can opt to use the serial bus to power the later gauges if you'd like (just need to wire things up a little differently). I'm not too sure what the differences between the v6 & v8 guages are, so someone else will have to chime in there.
