And just curious, assuming the original compression and cam, will this run on pump gas?

Mike, Sorry, AC Delco pump with the return line to the tank (1/4"). We are going to check the compression next week sometime with the Whistler. I believe Dan said he got static compression ratio measurements of 9.6 cold/10.0 hot on his '69 Firebird's 350HO, which is still standard bore with minimally cut heads. We're suspecting the same numbers from this engine. We drove the 40 miles back on whatever was in the tank (guessing 93 octane), but it didn't ever knock/ping since it was only 35 degrees outside and the timing advance is really slow. I hope it can run on 93 pump fuel.
