Hello People,

Have a 4.250 Cola crankshaft and 6.535 Eagle H beam connecting rods with JE wrist pins, .180 wall 52 S.  $560.00. :o

The crank journals size is .010 Rods/STD Mains internal balance. The 4.250 crank works very well with a 1.520 compression height piston. In a short deck block, use a standard 6.135 rod for short deck, 9.8” and .400 long for tall deck, 10.200”
Some 1.520 ch pistons require the use of an oil ring support system; some do not depending on where the wrist pin was programmed for the customer.
