Howdy all, I am just in the process of degreeing in a new cam into my XR8 & can't get a closer spot than 2 1/2 degrees advanced or 3 degrees retarded, the cam is meant to have -27 degrees BTDC @ .050'' but because of the geardrive I am using I can only get 30 deg or 24.5 deg BTDC, has anyone experimented with the results of advance/retarding cams in a 302w. I feel that it would be safer to advance it, but I have only played with clevo's in this dept.
any advice from experience would be much appreciated
cheers kenny
here's a shot of my newly ported inlet port.

Is it an option to have a new key way ground into the cam gear? Or whatever it is that they use? The alternative would be to swap them for some vernier gears that are fully adjustable?

they have multi ofset dowels, but it appears that they are only in 6 degree inciments, I will experiment a bit more 2morro with moving a tooth & backing up with the dowels.
but from experience 2-3 deg advanced wasn't the end of the world, only retarding it gave me grief

+/- 4 degrees should be fine, any more and you may run into issues though. 4 degrees will move the powerband by about 200rpm, advancing it will obviously improve low end power and probably help idle out a bit too.

well, got it in at 1/2 degree advanced by advancing it a tooth and retarding it 6 degrees, so hopefully I might be able to hit 300hp at the treads this time around still using E7 heads ,as I am not gonna use the vic Jr heads on this combo, yet!
cheers kenny
