L82 Intake and Exhaust manifolds

[James Price]

Hello all,

I'm trying to restore my 78 Silver Anniversary's L82 back to it's original configuration.

I'm looking for the correct Intake manifold. Seems like several were made but not all for the 225 Hp L82??? Which numbers were right?

I want to hold off on the AIR pump, EGR valve, etc..but I still need exhaust manifolds that will accept factory type pipes and work with the L82 heads.

Any advice???

Jim

There was one intake for the '78 L-82; casting #458520 (aluminum). It used casting #3932461 exhaust manifold on both sides, but they were machined differently - the R.H. side was drilled for two A.I.R. holes, and the L.H. side was drilled for four.
