Thread: will a reground stock crank work

Tweet

chinese cranks 4130 and 4340 more than 30+ of them in evey thing from 4.250 to 4.750 stroke in big block chevys street.strip. pull truck. air boat.sand drags. and more chinese H beam rods than i care to think of .yep it is all junk???? well they still sell the stuff ?and the Best cranks do fail. i have only see one crank crack 4130 but it did not fail it was in a customer 548 that went to 8000 all the time in a chevy 4 wheel drive full size pickup hill climber and have had gm steel cranks .040 rod and .030 mains that had a very hard life and is still good ? there is not one thing bad with gm cast cranks built many big block with them for mild builds that went to 6500 all the time getting a good grind job is the big thing . and oil clearances and damping the harmoncis. this will keep the crank happy .round here to turn a crank is about $80. looking for the cheap job is not the best .i will pay more to get back some thing thats is right

ok I'll make sure to tell the machinist to do those extras I'm know the pistons are going to be different then the stock cause im going with the dished keith blacks 5.7 rods just having trouble getting them in a kit already
