1971 and older pulleys had 1 hole offset-easily machined oval. not as easy on an old aftermarket aluminum pulley
Assume you are referencing the moroso pulley. I ran 5 bolts for a decade at 7500 rpm. The even spacing 72+ is my preference as that's what most aftermarket pulleys are.
We had a non symmetrical SFI balancer on the race truck with a symmetrical Moroso lower pulley. We just elongated one hole & indexed it from there.
I have done it both ways. I just had to pick one or the other. I find that the symmetrical is more common in the aftermarket.
I ordered mine from Summit a week before you posted. Yours is a few dollars cheaper, if I'd only known... LOL
I was hoping a high volume buyer may have convinced an American company to produce something. You do sell other brand engines.
