Brent Mills Brent you just dumped 600 in to the motor and STILL don't know what is causing the problem. Before you waste another 600 how about we find out what the problem is. T&D, Jesel and Erson for the best with Shelby behind them Erson is a bolt on there T&D and Jesel need head work to make them fit. If there is a problem with the new set you just got from Presision
oil pumps send them back for being defective. Ask George what to use. Sent that motor to George and get a new bullet for the car. It's time to take that horse outback and and put it out of your misery. Rick Lake
