stroker life span?

I was just playing Mad. Sorry about that crack.


Back on topic... The wear issue ultimately is ring seal. The only thing that keeps rings square in the bore are the skirts. This is why the diameter of a piston is measured there. They stabilize the piston and keep the rings stable. The longer the distance between the rings and the skirts, the more stable the ring packs will remain. The stroker pistons are made shorter, to clear the crank counterweights.
It's my opinion that with the use of a shorter piston the pistons rocks more both at TDC and BDC, and in addition, the sideways force on them is quite a bit more than a factory stroke engine. So you will have accelerated wear (when comparing to a factory setup) in the cylinder walls, the piston skirts, the piston ring lands, and the rings themselves. This is of course assuming the cylinder walls are thick and stable, and it was put to gether properly and the bores were properly cleaned, and it was properly tuned and the rings properly seats and were never washed out. You can't get something for nothing. The power results from the shorter life span and there's really nothing you can do about it except not build one. Which, IMO, is a shame. The stroker small block A body is IMO the ultimate dual porpose car. I've had B, E, A, and C bodies, plu a truck or two. I've built all of them at various times. Nothing is as all around fun as the 408/416 A bodies.
