I was wonderinig if anyone had problem with using a doubleroller timing chain and an ASP crank pulley, ASP says that they are not compatible together but, can it be modified to work ??? Need some input from guys that have tried this set up. Thanks

I think they'll work, but the collar of the pulley needs some shaving, I think. I thought I read something about that here LS1howto.com

yea like ben said you have to shave the snout of the pully down a bit.

But has anyone tried it on a truck to know for sure? Our pully is just a little different from the cars.

I did it on my truck. My neighbor has a small machine shop in his back yard so we turned the pulley down a little to allow for the distance the double row chain shims force the oil pump forward. I think we milled 3mm off to be sure we had sufficient clearance. What you do is measure the thickness of the shims and then mill that much off. It might have worked without being milled, but that would have required a trial fitting of the ASP pulley to be sure it didn't' interfere with the front face of the oil pump. I figured rather than mount everything and put the ASP pulley on the crank and drive it home to be sure it didn't hit the oil pump I might as well go ahead and put it on the lathe. It works well and the double row chain is high quality. The installation instruction suck even though they're written in English. I guess there is a difference between Austrailian English and American English because reading those instructions sure is confusing especially if you want to add advance or retard to your cam. Be careful with the shim that goes under the pump on the oil pump output port side. If you get that one on upside down you will reduce your oil pressure BIG TIME! While you have it apart you might as well put in a ported LS6 oil pump and a big cam so you don't have to tear it apart again later if you decide you want to install those things.
