[QUOTE="greg brillus, post: 165469, member: 597"] Its all a bit of a fantasy in a way.......the thing to remember with a squish band like on the TP top ends is........look at the possition of the band, verses the overall height of the chamber........It's not really ideal.......A lot of these early engines with big hemi heads tend to have a squish area atop the piston crown on either side.......Look at some Manx type pistons to see what I mean........On our race engines we are tapering the squish on an angle to direct the flow of gases more towards the chamber roof than just straight in and flat....... I tend to feel that a flat very narrow squish area could actually cause detonation due to the "Dieseling effect" that this tiny area might cause........All experimental of course. [/QUOTE]
