Cast Crank Strength

$250 for a set of hyper pistons. I e-mailed KB's tech dept and asked them how much of a shot they can take. I am not going to go to a 360 block. I want to to keep the 318 block.....that and I have 4 of them so I don't need to go buying another engine. I am not going to exaggerate that is lying and it's not right....only chevy, ford and import guys need to do that. As far as safety equipment I have no problem doing that...I already ahve the 5-point harnesses and the roll cage should be going in this winter. Upgrades axels are on the way.....going with Yukons. I already have the longer studs so I am NHRA compliant.....safety stuff and driveline strength go hand in hand and I'm not going to cheap out on that stuff that just being stupid.
