Vortec 454
 

Trying to find out if i can put an 88 TBI intake on a 97 Vortec 454? Will the intakes interchange?

arent 88 up vortec heads?

My 88 has normal old school peanut port heads. Steel valve covers even.

Oval port Vortec heads began in 1996.

I want to say there is something different about gen V 88-95 heads and intakes cause i know you can put a GEN IV intake on a Gen VI (Vortec) but not on a gen V for some reason. Might be able to find an aftermarke TBI Gen VI intake though.

87-91 TBI 454 is carb manifold with adapter plate, is quadrajet flange to tbi flange adapter. Sooooo, technically a newer quadrajet flanged manifold for Vortec heads would accept the tbi w/adapter. Or a square bore manifold with a different TBI adapter plate.

The throttle body on this engine is from a '90 C3500 cab-&-chassis GMT-400, the engine is a Gen VI factory replacement upgraded with Vortec heads, Mercruiser cam, and Edelbrock performer intake.

Gen V coolant passages are different. VI went back to IV style so IV stuff fits VI and vice-a-versa but V is oddball critter.

Ok so i can get the 97 vortec and put it in my truck with my old intake on it???
