Hi i hav a 1991 Z28 with a 350 TPI... My father also owns a 1986 Corvette 350 TPI.. My father told me that the 350 TPI is a corvette engine and was a special option for the Chevy Camaros....... Was the TPI a 80's early 90's Vette engine?? Also when did they stop producing the TPI? thanks alot guys for listenin to my stupid newbie questions

The TPI was introduced in 1985 & ran until 1992. The Fbodies first had it on a 305. Then in 1987 it was available as a 350 or 305 in the Fbodies. The Vette had the 350 TPI only from 1985-1991.

The 'Vette TPI motors got aluminum heads. So they're not quite the same.

TPI is not an engine, it is a fuel injection system.

yea, the motor is called a L98, but we knew what ya meant

also, the Corvettes got some minor stuff that was different than the F-bodys, like the fuel rails came out of the left side instead of the right like the F-bodys, they had a different computer that would mount in the engine bay, etc.

lol the L98 i knew that as well but is the camaro L98 pratically the same as a vette L98?? Like could u still considered it a Vette engine or no? Kids at school r wondering if this is a vette engine or not i hav no idea what to tell my friends what it is...... cuz it still the basic idea and looks of a vette engine..... soo i dunno..... thanks for responding so far guys im learning a lil bit more about third gen everyday as a rookie

well, I'm not to sure as to the exact differences other than the fuel rail and computer were different, as well as the aluminum heads. The 'Vette had like 20 more hp than the F-bodys IIRC.

But, its probably like the LT1s. You will hear every salesman around trying to tell people that the LT1 in the F-bodys is the same motor as in the 'Vette. Aside from many minor pieces that are different, the 'Vette motor is a 4-bolt main block, while the F-body's is a 2-bolt. This is one of my pet-peeves as it is a blatent lye. Sorry, just wanted to share that knowledge.

Partially incorrect.
The 1985 Corvette L-98 had iron heads. The aluminum heads became available in 1986 on the convertible 'Vette (or the coupe, but not both---I get it confused sometimes) and all Corvettes got aluminum heads in 1987.

if your asking if the L98 was a vette engine, the answer is yes. chevrolet never meant to put a 350 in the 3rd gens. the 305 was to be the performance motor for our cars. however, once ford came out with the EFI 302, chevy know they had to do something to compete, hence the L98.

Ooh I got one - The Corvettes came with a more tubular manifold, instead of our loggish piece of square junk manifold.

You can tell your friends it is technically a Corvette engine, but you should go on to explain that it was little more potent for the Vettes, as well as not being recognized by any Corvette enthusiast as a flagship engine

Exactly! What curt said.

Except GM cheated, IMO. Rather than competing fairly by developing the 305, they copped-out and dropped in "a 'vette engine," as it was marketed. And even then, the 302 could still hold its own. So the 305 could've too.

But the 'vette still got the new good stuff first, lol. The fbody's L98 was always a bit outdated by comparison.

truth is here , even no the 305 is called a boat ancher

you take a 305 tpi , gm installs a good cam good heads , better exhaust , easily that 305 tpi can be be ran around 260 hp stock , but no them ****** put ****ty cams in ****ty heads ****ty exhaust

oh well ,
