Hey guys, something I don’t understand. A 493 has, I think, a 6.76 rod & the block needs some minor notching. Yet a 512 has a 7.1 rod(?) & slips in without modification?
The Chevy size cranks are not weaker. The metal now a days is way better. I have a 4.5 stroke crank and the oil pick up boss is ground down almost to the threads. Kim
I have a Probe rotating assambly for my 543 and also for my 505 kit. All the rods are good nowadays. They do have a horse power limit. Uy what suits ur build. My next builds will be K1 or Molnar. Kim
