I'm buying completely new heads, so all head/pushrod considerations will be taken care of there as they want to know cam specs to buy the heads. Do the bronze gears last very long? I've read some that say they do and some that say they don't. I've also read that there are different alloys of bronze gears. Who makes a good one for a 440 then? '67 440 Satellite

In small and big block Chevys as well as SB Mopars with the drive gear at the back, it is a relatively simple matter to press on a gear because it can be made to fit over the rear journal. With the larger journals at the front of camshafts the inside diameter required for the drive gear would be larger than the gear itself.

I've found that Milodon's works pretty good and last for a few years. Make sure you keep the cam end play to a minimum (no more that .005"). Try not to run excessive oil pressure.
