On the other hand, Judson hoped to eek out a few extra ponies by running concave dish pistons instead of the more common reverse domes. "A concave dish sacrifices some quench compared to a reverse dome, but the Nextel Cup guys have been using them for years and say they're good for an extra 3-4 hp."
A quote made by Judson Massingill that is in the paper version of the mag. Article but does not appear on line is.
“Some people swear that a concave dish piston is worth some power over a reverse dome, but when five guys that finished ahead of you have reverse domes, it makes you think twice.”
