CAN A 390 CRANK TAKE .030 RODS AND MAINS WITHOUT WORRY? STREET MOTOR.
CAN ANYONE ID THIS CRANK 3196922? I THINK IT'S A 1969
Yes and much much more
is this part number a 69 or 70? I do not have it in front of me so I can't see the center counter weights to tell.
70 390 crank is #3196921
SO I ASSUME THIS IS A 68 OR 69. IS THERE A DIFFERENCE?
To my knowledge the counterweight was the only change...same stroke.
Is there any benefit for using a 70 crank over a 69 or are they jsut balanced different.? Does Bulltear sell Billet 390 cranks?
No more billet cranks for now. The only advantage is that you may not have to rebalance.
