Pete tells me 13:1 is the sweet spot for these Hemi’s. My plan was 12:1 and I’m now thinking just build it with 13:1 and live with it. I don’t mind mixing fuel as I do it now with my 12.5:1 511 wedge. Looking like CP will be the piston if a can find a shelf piston for this. Once I get the heads I can cc the chambers and intake to get a better idea on the compression and cam.
