440 Dynamic Compression and Pump Gas - 02/16/12 08:49 PM
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
