Check and see if the roller wheel you want will work with your cam. Different diameters change the rate of lift and may be too fast or too slow for best performance.




I just recieved a set of his Pro Sport lifter. They look pretty good the machining is great. I decided agaist the pros because my piston to valve clearance is on the tight side now(int-.060/ex-.090)and I didn't want to loose any. I don't think the roller on the Pros are wider, just a larger diameter with larger diameter roller bearings. The box said BAM Products. The engineers name is Brad Miller. Hopefully they hold up well. I usually don't like to be a guinea pig, but the price is great and they have the good features.
