You'll have to elongate the two center bolt holes on each side of the base. I believe the angle changed when they went to aluminum heads in 86/87.

WRONG!!!

In 1986 the center bolt holes changed angles in the cast iron heads used in the F body L98 engines. The Corvette aluminum heads along with ALL Gen I and Gen II Corvette intake manifolds retro fit back to the original, 1955, 265, as far as bolt pattern is concerned.

RACE ON!!!

As long as it is a Corvette L98, (as in the title to your post), and has aluminum heads, (like all 1988 Corvettes), you'll be fine.

I'm sorry if some think I was abrupt, but what was abrupt, was 89onlyZ51 jumping in, after the correct answer had been given, with false, erroneous, incorrect, misleading, and wrong, information.

RACE ON!!!

CFI-EFI,
I have sveral intake manifolds, about 8 plenums, at least 6 pairs of runners and 4or5 fuel rail sets. How can i id each of them as to what they are from (camaro or Corvette) and the years they will work on? The fuel rails are easy to tel the make but i have forgotten over the years on the rest. It is time to start selling off excess and i don't want to screw any-body up getting the wrong year/make.
