Mike, you still have the jeep?? Adam broken a piston in his. Come to find out that the engine is not boost friendly. Not just because of the compression ratio, but also the cheap pistons and the cam which has a 120 LCA that keeps so much exhaust in the chamber it rattles the pistons. Need less to say chrysler did as little as possible to get the engine to last with the power levels it has stock. With a power adder you will either break a piston or spin a bearing, cause of the tight bearing clearances. So, we are going to ditch the stock short block for a built 426 hemi with a more boost friendly 9.3 to 1. We will get the heads ported to the max. When all said and done it will have around 700HP with 5 psi, with the ability to run up to 10. The engine builder said that with the 426 it will be a monster at the track. I would have to say the nothing will keep up with it on the streets... We will keep the stock torque converter, because any higher stall speeds will break axles.. I'll let you guys know how it turns out.
