GM exhaust manifold cast #
I was just wondering if anyone on here could tell me what these ram horn style manifolds might have gone too? I was gonna use these on a SB motor swap in a fiero but I got the Big Block fiero so I dont need these. but the cast # doesnt appear to be on any websites
the number is
3992485 it is stamped with a GM I have the left an the right for the set. the left one has no cast numbers just the right hand side. any info an what they may be worth would really kick some major ass. thanks alot.
