302 Dwell issues-dwell numbers wander around....worn out timing gear on the cam?
I've posted this in the 302 small block section, but thought I'd try and get some of the slick guys advice....
I've got a 73 302...(has rebuilt 69 heads) just replaced distrib. (stock Motorcraft-professionally rebuilt) and when dialing in the point gap,
the dwell numbers wander around. My Pertronix Ignitor was defective, so I've re-installed the points until the replacement arrives. Vac
Advance tested fine. Could this be the timing gear is worn out on the cam shaft? I planned on replacing the camshaft/and timing chain/gear
with stock ones...what was the throw on a stock 302? I don't want to get into a discussion on hot cams and all that really, I just
basically want to get it running smooth again...This truck is a farm truck D.D, all I want is an original 302 Cam, or something not too
extreme that's going to open a can of worms on me when it comes to lifters, rods and the heads etc...
Thanks in advance for any help,
Jason
