Bought the 426 and now I am about to throw in the towel. I purchased all new parts, head, valves, piston, cylinder, and the crank was brand new when the motor blew up and ate the top end, I thought it was good but look at the attached looks like the small end is a bit cocked. didint like goinging the the cylinder very well. What do you sugest, new crank or just rebuild the crank? Know anyone good to rebuild the crank?
