just checking Summit racing and there are so many ATI superdampers for bigblocks. is there a superdamper that will bolt on and accept stock pulleys (alt and waterpump) on a street/strip '71 vintage 440 for my '70 bee? and is anyone on here a dealer for them? any advice on which one to buy would really be appreciated it's a stock forged internal balance crank 440. thx, dave
