I need the part number for the oil pump drive that goes in the lifter valley.

Thanks!

 

Anyone know offhand?

 

GM PART # 1103868

 

I was advised that the phenolic bracket on the top of that drive is subject to breaking on high HP LT1/LT4s. When it does, the shaft rises off the cam and then bye-bye oil pressure.

MORE Performance in Charlotte, NC makes a small billet piece of metal to go over the top to secure the drive in place. One needs a slightly longer bolt to through the metal piece to hold everything to the block.

When I did my cam swap and bought parts from Mike, he gave me one of those little jobs. Great idea for an engine saver.

 

Thanks for the suggestion Don Ill have to check that out.
