I have been looking around for a Tri-Power setup for my 283 SBC. I was wondering if it would be better to try to find a manifold that accepts 3 bolt carbs or 4 bolt carbs. I looked around but couldnt seem to find any adapters that would allow me to change between the two. Thanks.
alot of the manifolds will have both holes in them. I run tripower on mine & i'd suggest getting one with 4 bolt holes for rochesters, much better off. JimV
Offenhauser makes the adapters you are speaking of and I think you can either get them from Exeter Auto Supply or Hot Rod and Custom. Both are Alliance Vendors.
I've got the 3x2 manifold in stock for the 3 bolt carbs, and the adapters to use the small base 2GC carbs on the manifold. Dan Marvin, Owner Exeter Auto Supply
