RE;McQuillen manifold
I have the one that Rich cast & Tony did the finish on several years ago. No, it won't come close to fitting under a stock hood but will under a legal NMCA bubble.
Power, my .060 over race engine went from 11.1 to 10.8 with no other mods.
I've got several from Tim's buddy. Looking good is nice but his design is really good. Adding one of them to a set of out ported heads actually picked up air flow..
