Having trouble finding a LS4 oil pump?
I got a call from SPDC today about my order on hold... LS4 pump was on backorder. So after calling ECS, LPE, etc etc... researching the GM high volume pump (which LPE said wasn't much different than the LS6 but w/ a better seal for more pressure), I decided to call my local dealer.
Sure enough... I just ordered on... on w/ my cam install
PM me if you'd like to know where to order them
