My stroker crank was not a kit. I bought the 4.00 Eagle crank from Summit. There were a few problems.
I had all the pistons installed and was in the process of installing the Cloye's Double Roller timing chain. The lower crank gear, would not fit on the crankshaft correctly. It would only go so far and stop. My machinist told me, he could take some metal off the inside of the gear. After that. the crank gear went right on.
I thought I was gonna have to disassemble the engine.
Timing chain and cover installed. Put the water pump on. Everything going OK. I put the Harmonic Balancer on the crank, and noticed, it would only go so far and stopped.
Now what. The top water pump pulley, and the lower balancer pulley didn't line up. Eagle machined the crank wrong. Dave shortened the Balancer hub to bring it closer to the engine. After that, the pulleys lined up as they should. If I had to do it over again, I would buy the Scat crankshaft. I should have known. The boxes the Eagle Crankshaft and Eagle Sir Rods came in, said Made In China.
