The shop that originally built my SB 383 said the Mopar's seldom have block issues if you stud the mains. I asked about Mopar girdles at the shop that built my kid's SBC... he said he never sees crank or block issues with SB Mopars...
My engine is a mild 575 hp deal that will run just north of 7,000 rpms on a 1/2 mile dift track.
