hey svt4b why did your motor blow in the first place? Anyway I have decided not to run the ASP crank. pully (if anybody wants it is for sale) The only reason I was going to use it was a) power gains (not much iv heard) and b) the hope that it would cause a spun bearing or some thing so I would have a good reason to go 3.0 (the G/F does not approve). A dumb idea I know, cause I would proly end up facking my cams which I want to use for hybred 3.0. Personaly I dont think underdriving at "both ends" is a good idea so im not going to do it.
