Ok, got the engine, and all the parts to go with it. Since I have filed my request forms for more of a budget, in triplicate of course, and not heard a responce. I am assuming the finance dept (i.e wife) is denying any further expenditures.

I am going to need to make one of the following sets of heads that I have work.

There are the #15's - from a 1968 pontiac 400 CI, D-PORT exhaust ports, 1.96 intake, 1.66 exhaust, 92 CC combustion chamber.

Or there are a set of #46's from a 1969 400/428 CI, D-PORT 1.96 intake, 1.66 exhaust, 72 CC chamber.

Almost identical except for the combustion chambers. I want higher compression for more HP, leaning the go-with needle towards the 46's and the smaller chambers. But I am going to take the bore .030 over, which means new pistons, which I can use to get higher compression also, which means I can use the 92cc chambers and still have higher compression, and is bigger better here, more chamber means more fuel/air, and more boom-boom power (for better sence of a word).

I am going to go over this with my engine guy who is going to machine it, but I want to know what I am talking about when I go in and start rattleing off my thoughts...

Do I need to go back to engines 101 and sit in the front of the class this time?
