Forgive the stupid stroker kit question.

As far as balancing, i have two stroker engines running...one with scat 4 inch crank and one with a K1 crank.....scat I beam rods and KB pistons...both took a slug on mallory metal in the front and rear journal....the slug in the K1 was smaller then the Scat crank.....

I have another 408 waiting to be assembled....again 4 inch scat crank...scat I beam rods and SRP pistons that are lighter then the KB pistons...and again a slug of mallory metal....

If you buy it balanced....they used the box weights on the rods and pistons to balance the crank...dont know how it does not come with mallory in it...in fact the machine shop told me they have had to fix several of the pre balanced kits....

and for one last example got a 318 block with a scat cast crank 4 inch stroke waiting to be assembled...with scat i beam rods and Kb dished piston that weight in a 437 grams...and guess what it took mallory metal to balance it.....
