400 sbc crankshaft

Do they make a internal balanced crankshaft for a 400 (406) chevy small block with 5.7 rods. I have found them with 6.0 's but have not found one with 5.7. Will the 6.0 work ok on a street engine. Thanks

Scat makes a 4340 forged crank #SCA 440037505700 that will work with 5.7 rods. It's $599 so a tad more than a cast unit. The Scat cast steel 9000 crank will be just fine with 6" rods but you'll need specific fit pistons for the 6 inchers.

I personally would look for a complete rotating assembly...crank, rods, pistons, rings and bearings. Use whichever fits your wallet, I'll send you a PM for a phone number, good luck on your build.
