I recently built a 540 with a procharger after I blew up my 502. Take the time to build the motor to handle what you are going to do to it. If not you are pissing money out the back.

Thanx for all the input guys.My engine was build by Boyd's motorsports in lake George ny.There was no expense spared when this engine was being put together so i think i will be ok with the pro charger.Boyd is putting the F.A.S.T. fuel injection set up on it as we speak.Im already around 700 hp but need more.I sick of that little blue sutphen of morgans beating me LOL.
