Any of you guys know of an aftermarket balancer pulley for the 5.7 cars. I know there is such a thing for the trucks but it is not supposed to fit the LX models. Just from the smaller diameter pulley there is claimed to be a gain of 8 RWHP and close to 8 RWTQ. If it's true, seems like a decent gain for a couple hundred bucks. I'm always looking for cheap horses.
