I was curious to know if anyone has used the speedpro brand hyper pistons. I was looking at a set of the .340 dome to get my compression up on my 781 heads. Just curious about clearance issues with stock block and head measurements. They seem kinda cheap but I'm not sure if thats a good indicator of quality. Egay has a seller with new Lunati forged pistons that seem to get my compression where I want to be. $350 for the Lunati w/o rings or $250 for the speed pro's w/ rings.
