L98 Pistons.
Hey guys I'm new here. I have an 88 vette with the L98 aluminum head motor. My buddy with his 89 IROC has an L98. What I want know is, besides the iron heads, are there other differences with the motor. I am not entirely sure but I thought that I read the pistons where lighter? Any info would be greatly appreciated. Thanks.

i dont believe there is, internally. I dont know if they put the roller cam on IROC's or not.

Welcome to the forum! :) The pistons in the 1985 Corvette were forged, the other L98 Corvettes (86-91) had hypereutectic pistons. His IROC has different exhaust manifolds, and probably a more restrictive intake manifold.
