How would the added ring gap affect oil consumption on a strictly street motor?
With those "flat top" pistons, care to guess what the c.r. would be with my 97cc chambered heads?

David, I'm not an expert on the rings, but I did tell the builder that 95% of the time, it would be on the street and natrually aspirated, so I believe he was pretty moderate on the gapping. I had some 87 cc edelbrocks for this to run on pump gas, but had to sell them. I now have a set of 98cc 4x heads that I believe would be in the ballpark of 9.5: 1 with a thicker .041 head gasket for pump gas use. Hope this helps. - Adam

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
