Need some advice........

In the process of a few changes and I wanted to know what manufacturer I should use for the following items on the LS2.

1. Underdrive Crank Pulley
2. Double Roller Timing chain
I saw one Crank Pulley made by Power Bond for $200.00...not sure if it's a reliable piece or if it's overpriced. What have you people used for yours?
Any help would be appreciated.

I have the SLP underdrive on the 402 Stroker....I never will understand the double roller timimg chain thing.....we are running a helluva lot past 500 HP with the regular old single roller chain....Allen Nelsons monster drag truck putting out God knows what....LS1.....single roller timing chain.....many old timers and race engine types will tell you the double roller chain puts too much torque on the bearings......I think it would be a total waste of money .....however I myself had one on the LS1 for awhile

Hey...got it for free!

I have the SLP pulley on my 2000Z28 M6 with no problems. It has a bright metal finish which I like. Most of the others are black and of course look stock. I paid $213.00 for new off EBay.

I've heard some BAD storys of the PowerBonds coming apart and trashing the rad.

I would stay with the SLP!!!
The timing chain is a waste of time and labor!!!! There are many other mods I would do first!!! Unless your changing the cam there is NO need to mess with that!!
