I'm sure alignment is good. Last pass std flipped on its side but stayed on last 2 passes but thin gimler belt blows off every pass and that the one with the very wide crank pulley.

I agree you will need new belts anyways. GOTBOOST!New improved with Victor heads. http://www.enginelabs.com/mopar-big-bloc...t-of-necessity/

I agree you will need new belts anyways. Going to double check the alternator spacer. It might be flexing. Not sure. Vacuum pump definitely not flexing and with the wide crank pulley, it basically self aligns and the belt is almost centered on the pulley.

Have to order new belts anyway. Vacuum pump belt has to go on 1st. I do have a spare alternator belt. Always need spares.

I went through 4 belts usually once they flip I changed them out 71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it. 67 Belvedere that worked it's way in the 10's
