cranking compression

[SRT_DSTRHOLC]

What should cranking compression be with

Rhs heads chambers at 64
cam is xs282 244@50 67 ABDC @.015
kb 107 .40 over square decked
3.58 stroke

I'll guess in the 165ish range if static is 10.7:1

Should run on pump gas without much issue and good quench.

Actual will depends on gasket bore/thickness, piston in/out of hole, etc.

head gasket is .038, piston is 0 decked...I believe when I did a compression test it was at 180-190 but closer to 180. Im running 91 also

gasket bore size has as much to do with it as thickness.

4.100 I believe the Mr. Gaskets are.

Ran a compression test on similiar motor..yesterday

10.8 with eddy 63 cc heads....038 head gasket..

I was getting right at 165 psi...

but i think our elevation in vegas kills some of the compression...

Run on Pump gas?

Yes I do, but ok..Just wondering because I thought I read somewhere that it should be 190-200
