Newbie 318 piston question

@Garys72Duster
Ima thinking, if it was me; I'd be looking to borrow a second Compression Tester.

"Really healthy", to me, sounds like it could be a 292* cam. >To make 170psi at 5400 with an Ica of 72* would require about a 12.6/1 Scr. That's a mighty mighty small chamber.
>With a 268 cam, the Ica could be 62*, and the Scr would need to be ~11.6. This is about 62.5cc total chamber volume.
So yeah, I'm interested too . Cuz if you can get that to take WOT at full-timing, with iron heads ...... I got a 318 here in need of pistons .......................
