Cam Centerline questions

Trust your gut, that cam is too small. This combination will not run on pump gas. Sorry to say, but this only goes to prove what I have said all along, the cam people do not know how to grind a cam for pump gas. The lobe separation is to narrow, the duration is to short and the cam is ground with to much advance. The combination of those three will kill any chance with pump gas.

I went to two cam grinders when I had to set the 515 Ford up for pump gas and asked them their opinions for a grind. Hung up shaking my head. Called the third and just told them what grind I wanted without telling them what it was for. Single 4bbl, 10.5:1, 785 HP on 91 octane.
