All the topics i find on the net are for motors with timing chains or belts. How do you dial in a red 6 cam? Ive got a dial gauge and the motor's in pieces right now. I've also bought a set of adjustable gears (needed new ones as old ones were horribly noisy even though they were helical cut) and was thinking of retarding the cam 2degrees. Motor has an amazingly flat torque curve on the dyno readout so wouldn't mind moving the power up a tiny bit. Roughly how far would the band move with a 2 degree retardation? I certainly don't want heavy retard so it's all top end. Cheers. Edited by user Wednesday, 25 March 2009 10:26:13 AM(UTC)

most people i have heard is moving cam timing up to + / - 4 deg. otherwise you may consider another cam altogether. There are some computer programs on the web such as desktop dyno which, once you enter your specs will give you a theoretical HP and torq |
Old holdens brought on the spot, quick decision, cash paid. |

I can set the cam timing no worries, thats straightforward, but this time i want to dial it in to check if it really is correct when i line up the dots, or if i can optimise it somehow.
Well see tonight if i get the honing done in time.
Thanks. |
