hot rod crank for the 85'-86' racer

I have been rebuilding my 86' q'racer, and now that I have the engine in the new frame. I think there is a noise in the lower end of the motor, and I wanted to check the price of a whole new crank, but I have been unable to find one from any suppliers, and was wondering if any one out there know if they even make the hot rod crank. for the 85 86 model any more thanks in advance.

hot rods doesn't make a crank and rod assembly for the 85-86 model engines, only the 88-92 cranks. You will have to buy a hot rod and have it put on your original crankshaft.
