Re: New SBC Manifold with tooling
Yea Joe on the 90 cc chamber, I couldn't understand the 10 to 11 S.C. w/appx. 44 C.I. swept area and a dome with that much area (C.C.'s), now I understand why. Thanks Mark H. BTW I do admire your determination to go for it, wish you success !!!

Re: New SBC Manifold with tooling
This is what the casting looks like. Just got it back from the CNC shop. Been there for 5 months and couldn't get around to doing them. I'll try and find a more CNC cylinder head person.
The first picture shows my casting next to an AFR 227 head for size comparison. Note how by going with a zero degree (or 90 degree) intake face and then adding an additional .500" extension to the intake face I was able to make everything fit. This allows for longer valves, taller ports, and a recentering of the valve line in the combustion chamber. The biggest flaw to the SBC head is the 10 degree intake face which limits everything.
Not sure why my pictures came in upside down.

Boy that's a chunk of aluminum. Are these for a big displacement engine?
