Looking like my new pistons for my 383 will be coming from Ebay as of now. For a set of SpeedPro .030 over flat tops for my 383 is almost $300 at Summit and only $180 on Ebay. Also I'm looking for a place to buy my new camshaft for the 383. Either a Comp X4258HR or the X4260HR. Either of these is $245.95 at Summit, the joys of roller.
