I bought a old used forged steel KB Top Fuel fully counterweighted crank that had 4 cracks in it and sent it to David at marine Crankshaft CO in SO CA to fix it up
I took it to Summers Machine in Battleground, WA last year along with Scat H beam steel rods Mopar size rod journals rated at 1000+HP, JE pistons and it ended up costing me a tiny bit under $1800.00 for the balancing, they said it took a bunch of heavy metal to balance it whiney shruggy
I'll buy new stroker cranks from now on up
