1995 TPI

[jaros44sr]

thought i would stop by and learn something.......working on a 72 GMC Jimmy, with vortec heads, and tpi from corvette

Interesting ... I'm thinking the 1995 TPI is actually a LT1? I'm not sure what to about 1996 ~ 2002 L31 Vortec heads with a maybe LT1 intake? I'm confused as heck to what parts you are really working on. Do you have some pictures??

Ok, that makes sense.

I'm strictly a GM FACTORY ECM / PCM Tuner.:thumbsup: I'm 100% clueless about the Fast XFI 2.0 system.

well, when i started this project, i had no clue where i could get support, found the fast product and the rest is history....heard bad things about obd1, that was another reason going aftermarket. wished i wouldve know about you guys over here, i may have stayed stock

Nice...Very Nice!

So it looks like a TPI system (Upper Plenum and Side Runners) from 1986 ~ 1992 mated to a L31 Vortec intake manifold. I got confused with the reference to a 1995 TPI, which had me thinking LT1 Intake. See pic below.

thanks for the kind words, i just through something up on my first post (wasnt accurate), just so yous guys wouldnt think i was a spammer. Actually, it is off of a 1985 corvette( one year only), but i changed the fuel rails from a camaro, so i could get the fuel inlet on the drivers side

dont know what a L31 is
sorry for the confusion

Sexy! :rockon:

dont know what a L31 is ... sorry for the confusion

The Vortec 5.7 liter engine used in GM Pickups, Suburban's, Tahoe's, and Express Vans from 1996 ~ 2002 is also known as the L31.

Don't think twice about the confusion. We like to help, but knowing the parts involved is essential.

that'll be a nice engine; what cam did you throw in there?

[jaros44sr]

comp. cam, but ill have to look up the specs. i told them i cant have more than a 1/2" of lift for the vortec heads. im trying to build torque, not HP, installed2 1/2" corvette cast iron exhaust manifolds. Gotta move a 5,000 pound brick down the highway

thats also the reason i didnt fool around with runners

thanks for the nice welcome guys

maybe a Mod. can change my thread title........to avoid any future confusion, lol
