Did you work with Ken at OCG to come up with the Lobes and LSA etc for your cam? Also What is the intake center line you installed it at? |

I think this is the one Doug Dutra worked up with Ken many years ago. It's also called the RDP10, IIRC?? It has 210 deg on the exh lobe and 214 on the int. Not much above stock, and very similar to the smallest MP 244 deg, 0.436" cam from way back when. I might run this on a motor up to about 8.5:1 or maybe 9:1 (true static comp), then go to a bigger cam. Lou |

Quote: cam #2106 and I used the Exhaust pattern on both Intake and exhaust. .444 lift, 214 duration at .050 and 110 lobe separation. Intake centerline is 108 and when I installed the cam without any offset bushing it came in at 105 degrees.
It was 3 degrees here this morning, I just went out to the truck and pumped it 2 times and it fired right up. I am pleased with how it runs for sure.
