Boy did you guy open up a can of worms. I'm all confused now. I got a rebuild kit from ERW out of FL. and ordered a early timing set. When I got the stuff the set was in a box that looked like it was on the shelf since 1970 and was missing the crank gear. After bitchin I got a upgrade to a Cloyes roller. Early or late I do not know. It was shipped separate and wouldn't you know the empty box laid on my bench tilla week ago and got pitched out. So I don't know the part #. I have it installed at 0, and in the truck. I'm .040 over 9.5 c/r mild cam and 770 holley avenger.If my cam is still retarded I'll be pissed. How much difference will it make. I have the front clip off so I could go back in but don't want to. The truck is a 250 hd 4x4 that will be used for plowing snow, towing and playing.
Sorry bout the long post. Any suggestions?
