original '72 350 sbc in need of a rebuild, not looking for a race motor just a classic daily driver.
ditching the 76cc smog heads, replacing with a set of period looking 186 64cc heads 1.94/1.5 valves.
original bore has 8.5:1 with dished pistons, which will be replaced.
new cam going in, either a compcams 268h or a xe262h.
what is the max compression i can get away with on 91ulp and or 95pulp?
also, the american user manual that came with the car lists 91 ron for fuel, is that the same as our 91 ron?
