Tony,
Terrific information, I brought the block home last night so will continue to take measurements and compare them to yours. Thanks!
Your comments generate another thought, on a different issue.
I also have a rebuilt 1959 235 (with 848 head)in my '51 stock truck with a RV cam (212 @ .050, etc.)and the total available vacuum from the engine is about 13. You are running 36 degrees advanced on the stock distributor, what rpm does your engine run at?
Thanks,
Ted
