Re: perplexing situation
Fellas, I'm telling you, with the stock pistons, on a 34cc dome, you'd be *lucky* to see 28cc across the board (more likely gonna be 26-27cc each)...don't get wild on decking the block (a little is ok)...run the good Fel Pro .038" head gasket...and I bet you'll be right at 10:1, especially being we're talking 396s. Even better, go buy a cheap cc'ing kit (well under $100), and check it out for yourself...
I would recommend the Crane/GM blueprint '143' cam, as I believe it's a better cam and I'll just about bet it'll be cheaper...
We raced our stock spec L72 on pump gas all the time, except in the hottest part of the summer we'd add just a splash of race fuel...I'm not a fan of the octane booster stuff.
