Hey guys, the TRW book says the L2465 are open chamber heads only. But they also list a compression table listing 100cc heads (11.3:1 CR). They also list 106.9 which is a chamber size listing for BBC factory closed-chamber head.
So does that mean these pistons will or won't work with a set of '69 '290' closed-chamber castings? They CC's at 105-106 cc's. I know V/P clearence will be an issue too, but I can get a cam to match.
If anyone has used these pistons with closed chamber heads or has any info, any help is thanked in advanced.
