That's a nice cam. You probably don't need as big a split with Stage2 heads. With 10.5:1 SCR, DCR should be around 7.8.
He does have a custom cam coming, similar to the 288-94H, but tweaked for that combo. Comp is grinding it now. JW
No, not really, but that is not the worry on that block.. the backside of number 6 at just over .100 thick is.. That block would be fine for a stockish/mild build, with minimal overbore........ we talked on another thread about pistons at .008 oversize the other day, and you looking at a block that would want that 4.320 bore size. Assuming it has near perfect cylinder walls in it, with no pitting or damage.
While we are talking about flaws and cracks,have you guys ever seen a crack at the top of the front cam bore? This was NOT a race engine,just a core block.
I never broke a block but i hear the lifter valley is a potential weak place. That sucks. My third block is a charm. I am lucky to live close enough to JW and he sourced me a 75 blue block. -Thanks Jim. Numbers look fantastic! It is interesting to study the quality upgrades in the blue block castings, cylinders and lifters bores look beefier and more centered. I have some mods to do before I send it off to the machine shop for a 4.320 bore. Game back on
