Oil pump drive gear
Hey all, I was trying to source a new gear for the oil pump drive for the LT1, can a gear, OEM or better be purchased for the drive, or is it non-serviceable and only to be replaced as an entire unit?

Think I just answered my own question, although pricy from this source.

Re: Oil pump drive gear
The drive gear material needs to be matched to the camshaft gear material. If the cam/gear is a billet, then a melonized or composite gear should be used. the harder billet gear on the cam will wear out the bronze gear.
The stock unit (1103868) is supposed to be melonized though there are some reports of non-melonized gears. GM has a melonized gear you can buy separately and install on your existing shaft (19052845); you can use a composite gear (comp cams) though the the ID is larger than the LT1 so will need to have it bushed.
