393

  • Sponsors (?)


Need some seriously dished Pistons or some big chambers to NOT have 10:1 cr with a 393 build. Lol advertised duration...it is a custom grind. I'm sure they took all the pertinent info needed:crazy::crazy: I would expect at least 230's [email protected] and more likely over 240 with at least 10.5:1cr. Op might see 550 flywheel hp and close to 500 ft lbs torque.
I hope around 550 it's got flat top pistons i think it was around 12in a half to one with iron heads
