twin v-belt pullys on a paxton novi gss

Looking for a v belt twin pulleys on my paxton. It has a six rib pullyon it. But need to change it to a twin v belt pully setup.i tried paxton web site. But they dont have it. So if anyone knows where i can get one. Thanks for your help.

Why do you have to change out the 6-ribbed belt for the twin V ?.
I'm working on a Vortech setup for the small six and am interested.

thanksk

Because my 300 six has the belt driven pullys on the crank and water pump. So i dont want to switch them over to the rib style. It be to much work. The 300 is in my 65 falcon wagon. And its a tight fit.

Grainger has many sizes of 2 belt pulleys

Thank you. Do they have a website,where i can look it up.

Thanks for the website. Another question. Can i use a alternater pulley

you can use any pulley that fits or you can make fit, but the diameter is important

Ok thanks for your help guys

I measure my pulley. It is 4 3/4 round. And the pilot hole is 7/8. I went on granger. They dont have any that size. So if you guys can help me. I really appreciated
