Got my parts for new roller swap yesterday to finish things up. The comp bronze drive gear didn't come with anything to attach it to the oil pump shaft, I'm assuming I can just get a roll pin and stick in there or something else? Also how important is cam break in for a roller lifter? Same break in procedure as a flat tappet? Its a big block. thanks

becarfull putting that gear on a stock oil pump drive if you have a hi volume pump you want to get the milodon or Mopar performance bronze gear and hardend one piece shaft .
the stock one is not as strong .

It is a mopar performance shaft. I just figured the bronze gear would have came with more than just the gear. Thats what I get for thinking.

None, no cam break in with rollers

Thanks for the replys. Just got the steel gear off and damaged the shaft. Probably be the best to buy one already assembled.

mine cost me like $70 bucks and it was worth every penny! my engine made 600 hp!

You got the bronze gear and hardened shaft for $70? Where did you buy it? I buy mine from Summit and they're about $110. Please share your secret.

I think the 440source one is around $70
