i want to start a new project. put an lt1 i have in a 3rd gen and i was looking for performance parts for it today online and i'm not finding anything!! i want to do a stroker and get a little crazy.. but wow i thought there would be tons of stuff. does anybody know of or have a build for this motor i could follow that might have some part #'s i could look up as well? i even got on chevyperformance .com and couldnt find anything other then that oh so famous opti spark which still cost $200 grrr lol

thanks
brian

summit and jegs have parts

if you are going for head/cam combo then use Lloyd at elliot portworks

for the tune use Solomon at lt1pcmtuning.com

89fbrestor

i serched jegs, summit and jcwhitney. they have hardly anything anymore. about 5 years ago when i owned a 4th gen summit had tons of stuff. today when i looked they pulled up 2 crank options. iv heard of loyd's i'll have to check out his web site but. i'm think i might have to hit the 4th gen forums and find used parts. i'm bummin

the bottom ends are the same as gen I sbc with one piece rear main seals so any crank for those should work with the LT1. There arent a whole lot of crank options outside the standard 3.48" stroke or 3.75" stroke that you need. Not much more room to add anything else for the LT1. you can do the 3.875" for a 396 motor but doesnt give you that much more than a 383. You can go between 3.48 and 3.75 but that doesnt give you much advantage either over a basic sub 7K rpm 383 build with a 3.75" crank.

Pistons and rods are same as a SBC so nothing special there. If you were looking for a complete kit specifically labeled LT1 you may have issues finding stuff.

What are you trying to build?

Stock ported head castings are more than enough to make up to 450whp and then some. Advanced inductions has the records in LT1 n/a builds that I know of. Lloyd Elliott also does great work. Depends on what you want to do. There are some good aftermarket heads available if you didnt have good castings to get ported.

Intake manifolds, you can run a ported stock intake or possibly an LT4 intake setup or a carbed single plane. You can convert any sbc intake to work with an LT1. Just have to redrill the bolt holes and block the dizzy hole.

89fbrestor

orr why you gotta always make things so darn simple lol. thanks that was more helpful then you realize lolol. i did check out eliots site $ for power he's not to bad. so any 383 1 pc rear stroker will work and basically get me a decent cam, head work on the stock vortecs and i'll be good to go.

thanks

Yeah it should work just fine. Just balance it with the pistons and rods you will use.

Vortec heads? LT1's are reverse cooling so the sbc heads wont work on an LT1 without some major modifications.

89fbrestor

i thought the lt1 came with vortec heads... am i missing something? thanks

lunati397

lt4 hot cam kit lt4 knock module is a must if running headers Third gen hooker long tubes lt4 heads and intake afrs or trickflow now the gm 847 cam is a beast I think it has a different number now

most sbc parts are the same as for push rods rr centerbolt covers just when you get into ignition water pump and heads things are different

Orr89RocZ

LT1 had aluminum heads, but dont think they are considered a "vortec" head. Typically Vortec heads are the iron heads that come off the later model trucks up to 99 i think, but still GEN I sbc.

LT1 heads are sorta like the L98 aluminums with D-port exhaust ports, small 58cc chambers, but setup for reverse cooling and higher lift cams. They flow abit more than L98 heads and make 350whp with a big enough cam on stock castings.

lunati397

advanced inductions does alot with LTX heads

89fbrestor

lunati thanks for chiming in. was your build similar to I'm going for other then the turbos? if so could you share your info on what all you did?

89fbrestor

orr, gotcha. ya i have the iron vortec heads on the green car. they were port matched and polish with beehives and manely valves.. they perform great. very responsive. so are the heads off of a 94 lt1 going to be an ok choice for a 383. below is the kit i was going to buy. my goal is a solid 450+hp anything over 450hp is bonus. combined with this kit i was going to do a decent cam, headers and have the heads worked with a tune and calll it a day.

They are going to choke a 383 in stock form but ported out they are great. I still think you can get over 450hp on a 383 with stock heads but it will be crapped out by 5500 rpm. Most cam only setups peak in the 5800-6000 rpm range on stock cubes, but hold power to 6500 on some setups. Some have peaked abit higher like 6100-6200 but thats rare. The stock heads just dont have the cross sectional area and flow to support higher rpms. Ported out they can do whatever you please

Only thing to watch is the small chamber will require a bigger dish piston to keep compression near 11 to 1 or lower. LT1's can handle higher compression on pump gas with their superior cooling and witha large enough cam but You wont need that much compression.

89fbrestor

orr thanks your always a big help. so ebay here i come lol by the way that kit advertises 10.7:1 compression. any thoughts on cam for this set up. i'm starting this build tomorrow. so i'll start a build thread as soon as it gets interesting... or when parts start arriving... new parts are always fun to look at lol

lunati397

I had my 383 shortblock built by golen engines lt4 heads ported by advanced inductions self ported lt4 intake bbk 58 throttle body hardend pushrods a custom cam from golen engines simular to the gm 847 1.6 RR and a mail order tune from madz28 also electic water pump high volume oil pump ect ect it dynoed 550 to the wheels through a 6 speed

lunati... nice i sunk way to much money into the green camaro so i'm not going to get that radical with this one but i figure i should be able to do it for about 3k. i can do most the work my self including machine work to the heads so it will be fun to drive but not a beast like the two of you have. although my bike will beat ya both sorry just stiring the pot a little lololol

lunati397

with a 150 shot i took down a 06 R1 and we took it to about 160 plus mph lol we were coming from the track and hit the highway and it was on 3 times i put about 5 to 6 cars on him and yes I was spraying in high gears which is a NO NO

lunati397

I sold that motor and bought a house and in the process of building a new one its either going to be a 6.0 turbo or a 03 duramax still deciding and going to test fit the duramax sometime next month

89fbrestor

lol sounds like fun. iv got a cbr99rr.. built pretty mean i should be used to it by now and it still scares me it shakes my garage lol but bikes to cars isn't really fair.

89fbrestor

living quarter in front of keeping your motor... shame on you. you must a have wife or girlfriend lololololol mine lets me do what i want with cars sense its good clean fun and she doesnt have to worry about me. id take an evening in my garage working on a motor any day of the week over going to the bar

lunati397

LOL if you could see my garage I have no complaints I sold it because i was moving up and we moved and bought a house at the time since I have been collecting parts and tools to start my new project

And its a wife and she supports my addiction and I would much rather work in the garage all night than a bar club ect but one of the favorite things in the garage is my 1962 coke machine filled with beer lol

89fbrestor

"1962 coke machine filled with beer" lolololol now that would be cool lolol i just have a fridge *adding to list of things to get* lol

89fbrestor

well got my donor car for last night. now i have to decide on this lt1 or if i want to go a different route. its pretty solid solid and has a fresh paint job. the fun begins

lunati397

go with a 6.0

89fbrestor

lol not sure if that one will fit in my budget. plus i dont know anything about fuel injection and i admit i'll be intimidated to tackle it... not saying i wont but ......

lunati397

whats your budget and where are you located I have a few lol sitting around

Ive got a LS1 2 LQ4s and a durmax sitting in the garage right now along with a 1969 F100 awaiting a resto and a 1952 GMC awaiting a resto

Its amazing what you can get in trade for work on peopes vehicles

lunati397

stick carbed the LSx motors love that single plane with a 750 carb bone stock with a cam and you can get 500 hp crank

89fbrestor

i'm in michigan and i have a truck i actually have my boat online for trade on craigslist to see what motors i get offered for it. if your into boats mine is worth 2k. about 2500 if the seats were recovered. let me know

lunati397

what kind of boat year ect

I think an LT1 is a nice swap if you don't want the complications that go along with LS swaps, and you want good performance out of a stock setup. If you're looking for performance levels that require modification, to me, that immediately takes the LT1 out of the equation as a good starting point. Once you start getting into the heads/cam arena, most of the drawbacks to using a Gen 1 SBC go away, as do the benefits that an LT1 gives over that Gen 1 motor. While there is an aftermarket for go-fast LT1 stuff, it's expensive, and has a lot less to choose from than the Gen 1 aftermarket.

89fbrestor

jim thanks for the tips. i agree, i'm going to really think this one out. my green one is already pretty fast but it would be nice to have ... well another fast one lolol oh i'm addicted i admit it lol

89fbrestor

i'm finding a lot of 454's on craigslist today... any opinions on putting that in my car?

Jim85IROC

iTrader: (2)

opinion? Personally I'd be against having that kind of weight on the front end for anything other than a pro street or drag car. You're also talking about something that's getting away from being a bolt-in, although at least it'll use the stock motor mounts and there are semi-affordable headers available. Most big blocks also tend to have relatively poor fuel economy, though a gen 1 small block modded to achieve the same horsepower levels would likely be just as bad. EFI is also very expensive for big blocks, so for most people, a BBC swap means a carb, though that may be a non issue if you don't want EFI anyway.

ATX-Iroc

big blocks are expensive and pretty much need aluminum heads to stay anywhere close to a stock weight. the headers arent that expensive the hooker swap headers are cheaper than sbc longtubes for a thirdgen. I think lsx is the smarter choice but ive got a 402 on my engine stand, I didnt go 454 because of the expensive flywheel needed for a t56.

89fbrestor

hmmm well thanks for giving me something to think about... i'm not sure what direction to go in. i want to be in the 450 range and i really dont want to have to get into doing major stuff like i did on the green camaro. opinions on easiest 450hp build any motor?

Jim85IROC

iTrader: (2)

450? LQ4 and a cam.

Mkos1980

iTrader: (8)

Ditto to the above. It seems you cant build a LSX motor wrong. They always make power no matter what kinda mods you throw at it. (To a certain degree)

iTrader: (33)

Id say LT1 for a quick simple cheap build. The most exp. will be a set of killer AI ported heads and cam.

Id say 6.0 LSx with heads , cam , t56 if you have the funds for everything needed to do the swap.

Id pick the LT1 just cuz I have one. if I had 10k to drop again, Id do a lsX block and big cube 400+ build with my supercharger.

lunati397

hot rod mag just tried to blow up a 5.3 they put 26.8 psi through ti and got 1200 hp and couldnt blow it up they put 60 dyno runs raping the stock block and internals as much as they could then when it was all said and done they found out it was only a 4.8 lol its this months hot rod mag

pick up a 5.3 if anything they are real cheap

89fbrestor

great input guys. well i have about 2k to play with right now and i'm actually finding TONS of motors on craigslist for half that and most of them or built motors that never got finished... time to buy stuff everyone is hurting for cash(including me) i also have my boat online for trade for a motor and im getting offered some nice motors as well. i did see a few 5.3's and iv been offered average built 350's a few 383's and two 454's one of which is around 600hp as it sits and thats with out head work out of a bogger. *sigh* i'm kinda just wanting simple this time......

lunati397

stick with a LS based motor 5.3 lq4 lq9 and you can get power cheap and have a great motor to build on down the road

89fbrestor

looking for builds on ls motors. guys i'm new to wrenching and computers and fuel injection seem so complicated. but maybe its time i learn. i got started late in life when it came to working on cars. the motor i built for the green car... just followed the build lol. i'm doing some reading on it today and i'v found ls1's and 5.3's on cl just about all of them under 2k and most of them under 50k miles.... just worried if i can do this swap or not.

lunati397

you can pick up a 5.3 or a 6.0 at a junk yard for anywhere from 500 to 1200 and painless harnesses are very easy to install power and ground 90% of the time

and you have help on here

BTW our birds go to your brothers camp just about every night

89fbrestor

lunati thanks, maybe i will go that route then. what about tunning is that something i can do myself?

remember if you run in to "lance corporal" docherty slap em around a little bit he's just young pup who needs some military love lol he's just emailed me and said he's in kurdistan heading to the camp leather neck right now.

lunati397

with Hp Tuners you can do all the tunning yourself or datalog email it to a tuner and he will email you back and you upload it runs around 600 for everything

89fbrestor

cool info, thanks a ton. i'm emailing a guy right now about an ls1. i'll do some reading today find a build on here and see what all it takes to mount it in and get er running.

lunati397

its not third gen but ALOT of good info here
