If your cam gear is in good condition (You can check by looking through the opening with a flashlight, look for any uneven wear marks/grooves on the teeth. You should see a smooth and even wear pattern on the gear). If the cam gear is the original and the wear pattern looks good chances are you don't have to change it... this said, just make sure you get the proper "stock
" distributor gear...
I normally go to the junkyards and remove the distributor gears from the wags (Providing they're in good shape which most of them are). You could always bring your distributor to a parts store and get a new Cardone Distributor p/n 30-4891
for roughly $49.00
where I am is a little more spendy for the same distributor... Napas p/n
is NRD484891 $74.00
... (Can't remember if that's with the core or without
Bulltear is a good site/company to get stuff... I think BJ's also sells the distributor gears??? and the last I knew they're willing to match or better the competitors prices... (Don't quote me for sure as I have never delt with BJ's personally... But seeing some of their products and prices... I might have to try them out).
Just food for thought.
