Summit has a pretty good deal going on these pistons..The first is an SRP flat top..It has a comp. distance of 2.062 in. and piston head volume of + 6.00ccs...The Wiseco has a comp. distance of 2.050 in. and a piston head volume of + 4.00 ccs.. Both are flat tops and for a big block...Which would you choose and why?? Thanks!! Ted Need your rear end checked out? Contact Grizzly!!

Most aftermarket ones are .008" shorter than stock so that will play into it, if you're trying to keep any milling done to the block to a minimum.

Ted, Why don't you quit diddlin' around with flat tops and just put DOME pistons in it? These are Ross #99501, won't fit your rods though, .990 pins. You can use #99500.

Bobby...I didn't go with the stroker...I know it would make more power but I really don't want to go that fast...The car just needs to be consistant..I have been buying a few trinkets all winter...My last major purchase is the pistons...Talked to the body guy last night and as soon as it warms up a bit,it goes in for paint and the Hemi front end treatment...Should look pretty good!!

Mpar65, FWIW, Scott did a CR calcutaion with my pistons sitting .010 in the hole, a 039 head gasket, and figured a 74 CC chamber and came up with 11.09-1. When we actually milled the heads they cc'd at 64.6 cc's and he racalculated and we now have 12.05-1. I'm not sure how my Pro Tru pistons compare with yours as far as vavle releif volume but I would think your problably in the 11-1 range.
