I know there's a similar post already on here, but I would like to have someone double check me. I used an online calculator and came up with 8.53:1 DCR.

Cam Card




Static CR 9.35:1

bore 4.35
stroke 3.75

Here's the actual info after degreeing the cam:

Int open - 1* BTDC
Int close - 41* ABDC

Exh open - 54* BBDC
Exh close - 2* BTDC

Lobe centerline - Int 109* ATDC
Lobe centerline - Exh 120* BTDC

How will this be on pump gas? I read that 8.1:1 DCR or so is good. Is mine too high? What's optimum?

Thanks
