Advice on stroker kits

471" with the 6.535 BB Chevy (2.2" crankpins/.990" piston pins) rods works awesome. Enough piston skirt and lightweight assembly. In an RB block you would use a 7.1" BB Chevy-spec rod to get a lightweight piston with skirt stability. 440 Source kit should be fine, get the rod ends checked and verify the balance. I prefer ROSS pistons, so I bought the rods and crank from 440 Source and did my own balancing with the ROSS pistons. Enjoy!!
