LT1 S-Series

[BlazerINtheWork]

anyone on here done an LT1 swap in an s-series before? just wondering what year motor to go after. like either a vette or an f-body, i've heard the vette ones are better for an s-series(an fullsizes from what i have read so far). i also do not know the differnce in the years of the LT1, if anyone has a link on it post it up so this poor n00b can learn. i would also like to use a 4l60e since i have 2 of them and its what came in my truck in 94.



thanx guys

I have, but you knew that from BL

I put a 93 LT1 Corvette setup in my 92 C1500. Piece of cake. Had Street and Performance burn me a chip for my ECM with the VATS disabled. The Corvette transmission is a little different than the Camaro. You may have to modify the transmission a little bit. The connectors are different, I believe. 5 connectors layed out in a circular pattern vs. the square 4 pin pattern. Try to get the vette transmission if you have a vette engine and PCM. Later model LT1 engines have a OBDII and are programmable. OBDI will require custom burned chips. If I can sway you, forget the LT1 direction and go LS1 or Vortech. You won't regret it and the conversion will be much simpler. LT1 is old school and not exactly the wave of the future. LS1 engines are simpler to find, also. Salvage yards are full of LS1/LS6/Vortech and the newest arrival of LS2 engines. GM only is required to make replacement parts for LT1 part through this year and you may lose your GM supply line on fresh parts. I am leaning towards an LS2 on my next conversion. They are 400 HP straight from the factory. Beat that for less than $7000 including the initial cost of buying/modding/installing an LT1 and then consider that LT1 is about 100 pounds heavier and you are going to have to lug that weight around.

To stay emissions legal if you are worried about it, you have to have a same year or newer engine to put in your vehicle.

If you want ease of tuning, easily accessible knowledge, and loads of performance parts, I would stick with a 94-95 engine, or go with a obdii 96+, but convert it to an obdI setup.

As far as the camaro vs vette, the vette has all it's accessories mounted up high on the motor where as the camaro has them mounted low. You will have to notch the frame for the a/c compressor on the f-body engine, but not on the vette. the vette motor will cost you more and not really provide any better gains.

Go to www.v8s10.com and buy the swap manual, there's a lot of information in there you could use and would answer a lot of questions.

If you do go w/ the 94-95, look at getting LT1edit or TunerCat editing software, you'll be able to tweak everything in the motor, it's great! or if you don't feel comfortable doing that, go to www.pcmforless.com and talk to Bryan about getting a tune. You can remove emissions stuff you don't want to install and never get a ses light.

I've done the swap start to finish and can help answer any questions, so fire away! (blew a head gasket and did the LT4 conversion on it, then sold it to make room in the checkbook for my little girl, I miss it, but the trade off was well worth it.)

One distict difference between the Vette & Fbod LT1 is that the Vette LT1 block came with 4-bolt mains while the F-bod/ImpalaSS was a 2-bolt. The optispark is also different between certain years, 95+ have a vented unit which lets moisture out which was an issue on earlier units.

1st post BTW...hello!!

95 was good year. It does have the vented opti-spark which is very important. I have one in my s-10 blazer. My Webpage

I used the f-body because it was cheaper due to supply and demand. I have since changed to a lt4 based 383 stroker with afr heads.
It took me 5 weeks for the initial install. The trans is the weekest link and the vette trans is
supposed to be the stronger setup.
