mirror image -56cc pistons
How high can the wrist pin be with a lt1 mirror image of the combustion chamber in the piston(for high boost integrity)? I need to order a crank and I'm stumped on how much stroke I can have. Thanks -Tim

I like the direction your taking, small chamber and big rev dome. It could help direct more cylinder pressure at the piston. But a neg 56 is alot! unless you have 40cc nascar heads! :chevy

Re: mirror image -56cc pistons (Baldturbofreak)
Try calling Diamond. I know they've done Buick dished pistons that copy combustion chamber shape. The numbers .150" to .250" at thinest portion of the piston face are popping into my head. .150" on a normally aspirated or small nitrous piston and .200" to .250" with a high output piston.
I'm in the same boat. I'm going to need a set of pistons to go with a 38 cc chamber for around 9 to 9.5 to 1 compression, with as tight a quench area as possible.
