I'm swapping in a 95 SC engine into my 92 SC. I've sent the exhaust manifolds from the 95 engine to a guy in New Jersey who ports heads and exhaust manifolds. This is the first set of SC manifolds he will be doing, and he has a question. He wants to know the I.D. of the tube the bottom of the manifolds bolts up to, so that he can know how much to open up the bottom of the manifolds. Sorry about the lack of SC knowledge.
Thanks in advance for any help.
