Steve, why not use the heads from the 67 273, they should be the 920 head with the small chambers... The book says that they are 57 cc, but mine measure 63...

Then pop in a set of Rhoades lifters with your cam, and you should have some good low end grunt...

IIRC, he has a solid lifter cam now. I always thought Rhoads were only for hydraulic cams....??

The 302 chambers are the same size, I do believe: 63-64 cc's typical.

FWIW, the 57 cc is from the IHRA or NHRA specs as to how small you are allowed to legally reduce the chamber size.
