273ci thoughts?

Sealed Power 526P or 526AP are 9.0:1 (1987 Dodge 318) Yes they are flat tops and would work great with those closed chamber 302 heads that came on them. 920 heads or a 1966-67 273 head would work well.
I have a 67 273 now...you saying go with the sealed power pistons and my stock heads (freshened up of course) would work well?

Also, the 273 vs. 318 crank snout and relationship to my 904 trans...I'd be best running my 273 forged crank in the 318, no?
