I get paid next Friday, I've been eyeing this mod for a while over at TSP, which do I need? I'm lost with this stuff, and what belt? Noob questions, but I wanna know beforehand, thanks!

 

Anyone?

 

89.5" belt for just the UD crank pulley and 90" if you run the ALT pulley as well

 

Youre going to need a new bolt, a shorter accessory drive belt, and a shorter a/c belt.

This link should show you what you need, as far as belt size: http://www.aspracing.com/belt.htm#ctruckbelt

Don't look for any huge power gains, but every little bit helps imo.

 

you are also going to need to get the pulley install tool from Scoggin Dicky.

 

i think slp is a better choice. on the fbody ls1 the asps were known to throw knock sensors.

 

This^^^ I did notice that the rpms pick up slightly faster when I first installed my asp pulley had on for yr and half haven't even had a check engine light

 

Or you can make your own for relatively cheap, hardest part is finding the threaded rod.

 

Thanks for all the info guys!
