408 stroker engine build

The Scat stroker kit comes with the KB 745 step dish forged pistons, Scat I-beams, and Scat cast crank along with bearings and rings. You need to have a reputable engine shop balance the rotating assembly. Don't pay to have Scat do it they do a horrible job and when you call and complain they do nothing so don't let them balance.

It makes a lot more sense to buy new Scat I-beams instead of running those stock rods. The Scat rods are lighter, stronger, and you won't have to notch the block for rod bolt clearance. You should have the block line honed and put some ARP main studs in there too.
