Whats the Difference between the SFI certified one, and a non SFI certified one? And can someone give me specific part numbers i could take to discount or advanced auto parts so i could pick up the belts. Im getting just the U/D crank pulley. Im going to get an ARP crank bolt, im taking no chances.

Also what tools are needed for the install? And does anyone have a writeup?

378K4 Belt for AC Pulley
760K6 Accessory Belt for ASP Crank Pulley Only
770K6 Accessory Belt for ASP Crank & ASP Underdrive Alternator Pulleys
755K6 Accessory Belt for ASP Crank & ASP Overdrive Alternator Pulleys

Those numbers should work at both AutoZone and ORieley's

Yes i know this, i read it. I wanted to double check and make sure its correct. If i just get the crank pulley, which belts do i need, just the crank pulley or the crank and AC pulley?

If you get the underdrive crank pulley, you need to buy both belts.. They both being spun by a pulley with a smaller diameter..

Checkout www.thunderracing.com
They have the belts you need..

LS1ownzYOU, for what possible reason would you think that Nine Ball's info isn't correct? Watch out.....jrp might swoop down and lay the smack down for not utilizing the GODDAMN SEARCH BUTTON.

I did utilize the search button and saw that all, i just wanted to double check and make sure its correct. Everyone makes mistakes, so i wanted to make sure nine ball didnt.

Are the two belts needed for just the Crank pulley? Im also going to get the ARP bolt.

LOL yes, they're both needed. This question has been answered once in this thread by Z28Venom.


You gotta read man. People may include more information then needed sometimes, learn to pick out exactly what you need. My bad if I jumped on you unneccessarily about the search button....but if you used the search button correctly, then you would have come up with the right numbers. Then taken Venom's advice and checked Thunder's website, and found exactly which belts are needed.

I almost never jump on anybody about the seach button, because this would be a really quiet place if nobody could ask questions that hadn't been answered already.... But that was funny.
