Well I posted a month or two ago about the problem I had with my keystock on my camshaft not being long enough to catch the fuel pump eccentric. Well I failed to mention I have a double row timing chain. I looked in a book at the local library about hot rodding a small block mopar and I saw in a picture g how the factory timing chain sprocket sits back farther on the camshaft snout. I will try tomorrow or Monday modify a long piece of keystock by slowly grinding it till it has enough hanging out of the end of the snout so that it can catch the fuel pump eccentric.
