Well, since I needed a cam anyhow, thought it was a good idea to mildly improve it rather than put a stock one back in. Russ Martin reccomended his "425" cam and estimated a 4 degree offset keyway would work if I was keeping the stock timing gear set up. "Degree it in to be safe", so we did and found it needs another 4-6 degrees, and the new link chain with melling steeel gears is sloppy to boot. Anyhow, builder reccomends a timing chain set that can be adjusted for this cam, of course Russ has one for $190 plus shipping........but I gotta stop this bleeding somewhere. Does anyone have a more cost effective alternative or solution? Or any experience based advice on how to NOT waste anymore money on this nailhead?
