RE: piston weight/rebalancing/Silvolite problems By Travis Miller - 10/29/2004 6:24:57 PM; IP 152.163.101.8 While there maybe a balance problem, you should be checking the compression with these pistons as compared to your OEM ones. I checked a set of their 390 4V replacement pistons and found they held very close to the same cc's as the dished 2V pistons I was replacing. The area between the valve reliefs is lower than your old OEM 4V pistons coupled with the fact that these pistons had a more deck clearance giving less compression since the piston is further down in the block. Using these pistons will give you the same compression as a 390 2V with dished pistons. According to a Silvolite tech rep, this is all done on purpose. I sent mine back and used Speedpro pistons.

This thread, so far...
