Attached are the compression worksheets I created. This is the engine in previous posts with the Arias forged pistons, shaved crank, originally had a F10 flywheel & clutch , I'd already stole the Cannon single sidedraught manifold for the A15 in the car, H72 match ported head, etc...

I'm wondering if anyone has ran a similar setup w/a real worked up ratio ? I cc-ed the combustion chamber, piston volume, negative deck clearance volume, calc-ed the head gasket (Felpro Printoseal) managed to buy another NOS one - all metal gasket @ .041 compressed thickness. I've clearanced the pistons and head with clay so I know what all those numbers are now.

Have to talk to Delta Cam as its a fine line between grinds for above 10.5:1 and below.

Interested in how this will run. Obviously it'll need as high an octane as I can get but I think pump gas will be fine. Lookin for real world experience , thoughts anyone?

thanks,
evan
