Ok so i got a nova top motor (i got it used from a friend), 5 port motor that has been modified by ron paris, it has paris comp ingraved on it, and i need to get a new crank for it seeing as i took it apart and found a harline crack next to the port on the crank. Any one know were or if i can buy just the piston sleeve and crank that are modded by ron paris already, or am i better of just getting a new P/Sand crank and getting it by someone else.
Any help would be great

Thanks
Lee
