Talk about a cluster ###. I put on the 4 hole adapter but it just isn't right

At least the aluminum would pull some weight, run cooler and hopefully flow slightly better. The big benifit I see is getting rid of that stupid 4 hole entry of
the manifold.

I just don't have the experiance with these bow tie engines yet. I need to pick
some brains that have that experiance.
well sorry i can not tell you what you want to heari have been building bbc for 30 years from 396to632+ and was a merc tech. that carb will not know about the 4 hole spacer it going to work long as its not sucking vacuum . your going to have the cool look with a alum intake but and you could pick up some hp but to turn that in to MPH on the water would take more then a intake change to make it worth the money and time. stuff a blower on it now then you will have some thing
