No problem! I wouldnt like to get that much advance, maybe try welding it smaller? I tried mine higher and that curve fell off a cliff at around 4300. Ive got a .40 over 273 10.5/1 with a compcams hydraulic .454/.454 with 3.23 and a stock converter. Im going to over haul it with my magnum goes in next month and try a good mechanical/solid cam.
