LT1 intake casting differences?????
Can anyone tell me what the difference's between the 94-95 and 96-97 intake manifolds? I was surfing ebay and ran across a listing where the seller says he has both styles and the buyer can choose.
I am wondering since the LT1 I have is a 96, and I'm running it with a 95 PCM and concerned that the intakes may be different and have different sensors and such.
This is what he had in the listing:
1994-1995 10108630
OR
1996-1997 12552138

No differences in the castings unless it's a '93 model which doesn't have the crossover in the back of the intake.
Only difference is the LT4 intake which has larger ports than the LT1 but also requires LT4 heads.
