a 1.908 piston is taller then a 1.848 piston.
therefore it will have more compression then the shorter one.

if your looking for every last 1000th of a horsepower a dome might block it, otherwise its them or the sealed power forged flat tops and then have NO valve reliefs... I went with the domes because of the reliefs.



Okay, I see how the compression distance of the piston computes now. That is good to know and definitely moves the Federal Mogul pistons off the already short list of options. Does anyone know off hand what the compression distance is of the stock HP pistons for comparison sake? Also, is the compression distance measurement the distance between the centerline of the piston pin bore and the top of the piston?

Thanks everyone for all your help.
