Ok, I have a 350 block bored .030 over, block casting number 3970010 (hecho in mexico). I know that this motor is out of a 72 chevy truck and its a 4 bolt main.

My question is will I be able to swap this motor into my 92 Camaro RS 305 TBI. Someone told me that I could just take everything off of my 305 and put it on this block. However, I am not sure if I could since this is a generation I block. Is this possible?

If it is, I know I should change to a high pressure fuel pump, I would change the cam and the heads. Is there anything else I should change and any recommendations for a good set of heads for this motor?

ditch the TBI, the block will bolt right in, it has a 2pc rear main seal, your 92 came with a 1 pc rear main block, not a big deal, but you will need a flywheel/flexplate for a 2pc rear mainseal on the 350 block.

are you planning to swap internals too? cause they wont swap over.

What are you trying to do? drag car? pass emissions? streetcar/handling?

Right; same as the block in your RS.

Yes, everything will unbolt from your 305 and bolt to that block, with only one exception; and that is, the roller cam apparatus. Every mount, sensor, wire, accessory, and whatever else, will swap right over.

There are LOTS and LOTS of "good heads". The best ones, however, will depend on what other changes you want to make to the car, and what you're going to use the car for; and of course, how much you're willing to spend.

Not sure where you're going with the whole fuel pump deal.... yours is in your fuel tank. No connection to the block casting.

Basically I am just looking for a little bit more power for a street driven car and I would like to keep the car emissions legal in CT. I already have changed the entire exhaust system on the car (headers back) and I am planning on making my cowl hood functional with a k&n air box.

I am planning on putting an aftermarket cam in and heads on the block, what else would I need to put into it that would not swap over from my 350? (I am new to this)

As for the fuel pump, I was told that my fuel pump on the RS would not work in a 350, is that not true?
----------
sorry...I don't mean in the 350 like it will be bolted to the motor, I am just told the fuel pump I have is not sufficient for a 350

im gonna go out on a limb and say whoever said this meant that the feul pressure from yourelec. pump in teh tank will be too much for a carb.. geta feul pressure regulator and that will fix this problem... unless you are staying tbi then i have no idea where that feul pump idea is going either.. what kind of tranny do you have and is there any work into it? most ppl dont understand you cant just beef up a motor witha stock tranny.

ItalianZ32

Ok thanks for clearing up the fuel pump issue. I will probably end up staying tbi if it means that I will be able to pass emissions, because this is going to be a street car. As for the tranny, I have the wc t-5, which I know will need some work when I go bigger motor. I need a new clutch right now, so I plan on getting a good clutch which should help some, but I am thinking down the line of swapping in a t-56 out of 93-97 f-body. I hear those are an easier swap than the newer t-56. Basically, I was just going to hope my tranny held up for another year or two while I saved up for that swap.

Also, to clear a few things up, the block I have comes with the crank and pistons. After that I was planning on getting aftermarket heads and a cam and then swapping over my tbi unit from the 305. Anything major that I seem to be missing that will not swap over?

Stock TBI pumps tend to not provide enough pressure/volume for a healthier engine than the stock 305.

Your flywheel won't bolt up. You need a two-piece rear main seal type flywheel, such as used on '83-'85 3rd gens. If you go T56, it has to be from an LT1 equipped car (unless you're up to a lot of hassles). I don't know off the top of my head if a standard 3rd gen flywheel will work with a T56.

The dipstick will be on the driver's side, and get in the way of the stock exhaust manifolds. But, since you're going to install headers (right?), that won't be a problem.

ItalianZ32

Thank you very much for everyone's input. Since I will be installing headers, it looks like the major parts list I will need is:

1) flywheel
2) new tbi
3) heads
4) cam
5) computer from 350 (?)

everything else seems like it will bolt up from my 305. As for the t-56, yes I will definately get it from the lt1 car, but that project is going to have to wait prob until next winter. Thanks again for all the help.

what about headers and full exhaust? Open element? Be known that your current engine has a roller cam, the new one will be flat tappet.

im not too familiar with emissions around your area but i dont think it would be much different than colorado.. if your keeping the tbi to pass emission im confused?? is there some rule against carbs where you are??.. you will save more money and get more performance for cheaper (not saying you cant tweak a tbi for it) with a carb... going carb saves the hassle of ecu tuning and even buying a tbi unit to provide for the bigger 350... but also i am partial to carbs because its just less hassle to work with

Just wondering what is different on the 83-85 3rd gens than the 82 3rd gens?

The T5 wasn't offered in '82. I can't say with certainty that the flywheels are different, just that the '83-'85 will work.
