I'm not personnaly doing this mod but i was curious on what I would need to convert to a LT1 from a TPI, also maybe what I can re-use and if it would pass Smog/Emmissions, (without having hook-ups).

thats a great source but one problem is, thats for a 1st gen, says nothin for emmisions or the wiring and such involved in a 3rd gen

I think you misunderstood what you read. 1st gen means a 1st gen smallblock. gen 2 is tha lt1 and gen 3 is the ls1. A 350 or 305 in a third gen camaro is a first gen smallblock. I know the the lt1 intake is not emissions legal because you can't use a egr on it( I think some people have talked about a corvette type egr but I don't know anything about it.)

yeah what i was trying to say...

hell my 97 anniversary edition lt1 has an egr on it hmm and they are very much so emmission freindly thats why there are so many fuggen wires attached to the ***** and i think if he does a search there is something about fitting their intakes or someones modified intake and gen 1 engines too

sorry, I should have said a modified lt1 intake. Once modified for the distributor there is no room for the factory egr. Like I said john's site should tell you what you need to know. I'm sure a email to john himself should get you any other answers you need.

I think he is asking what has to be done to put an LT1 engine in his car - not just an LT1 intake swap. There are several posts on this. I strongly considered it while parting a 95 Trans Am t56 car, but I didn't do the swap due to not wanting to notch the crossmember for the A/C compressor. As well as the fact that you can accomplish better results with a std small block without all the hassle. It's cheaper and easier to upgrade an L98 than to swap to the LT1. Besides the intake difference, (which can be swapped as mentioned) the only other real improvement on the LT1's are the heads. I know the claim better cooling, etc., etc., but really a L98 short block with improved heads and intake will do just as good of a job. If the LT1 was such a great design, why did it get aborted after only 6 years of production? Also, why did it not replace the older design engines in the truck/van lines?

hmm alright cool, thank you all for the info, it got me thinking alot, but my main question is, would it be legal to put a LT1 in a thirdgen

The general rule is that a newer engine in an older car is legal, while retro fitting an older engine into a newer car is not. But - emissions guys can rarely (RARELY) detect this. It is just not what is being looked for.

I totally agree. I am in the middle of a LT1/T56 deal (got both for $1000) but Im only keeping the T56. I plan to re-sell the LT1 alone for $1000 (free T56 is cool with me! hehe). I thought about swapping in the LT1 but its really not worth it if you want to keep A/C. And what you said about power potential is dead on. The LT1 makes more HP than L98's, but the TQ numbers are areally close. So you are only a few parts away from making the same power as the LT1 with your L98 (starting with the intake hehe).

sweet, so i can drop in a LT1 and still go pass the visual for emmisions ?

I don't what your smog regs are but generally speaking as long as you have all emissions equipment intact for the engine(or car which ever is newer) your probably okay. Your best bet is to ask a smog referee for the exact regs and requirements.
