What size belt are y'all running with the 3.4" Science of Speed pulley? for the Novi 1220/1200, part #?

thanks

 

anyone?

 

the best I cant say is ask SOS...sorry when I ordered my pulley I said I need the matching belt.

 

That's the one size I don't have, sorry!

 

what belts did you get for 3.2" & 3.6"? I'll pick one in the middle

 

I believe its a 390 belt. What ever size you have (4060405) use a 390 at the end. I think thats close. I box every kit but don't know all the belt sizes off hand.

Actually what size do you have now and what pulley, i should be able to tell you from that!

 

hey Jeff, right now I have a 3.8" pulley w/ Dayco 5060405 (6pk1030) belt.. thanks

 

I don't know what size they are, but they're Goodyear Gatorback belts.
4060400 is the number on the belt for the 3.6".
4060395 is the number on the belt for the 3.2".


395 is too big for the 3.2". I'm already at the end of the adjustment on the tensioner pulley and can't tighten it further. So that might be a good choice for the 3.4". I'll probably try 390 next on the 3.2".


You can order them from Amazon and maybe even find them locally.

 

i have a 3.4 pulley with a belt that fits. its a dayco belt. ill check the number and get back with you.

 

thanks in advance
