Lunati Sledgehammer Rotating Assembly
Anyone ever run a Lunati Sledgehammer Balanced Rotating Assembly? It comes with a Sledghammer 4340 crank, Forged I beam rods, and TWR forged pistons. I was also looking at the Eagle Balanced Competition Assembly which includes Eagle's 4340 forged crank, 4340 h beam rods, and SRP forged pistons. My speed shop said that Eagle cranks have to be machined even when new, so I don't know if I would be better off with the lunati assembly. Would that be overkill. I'm going to building a 350 and the cam i plan to use develops 420hp but delivers power up to 6200rpm. I don't plan on using NOS, but who knows in the future. The local speed shop recommended using a forged assembly for durability since the engine would be spin higher then 6000rpms. I'm not sure if my block is a 4 bolt or 2 bolt, but I will have it converted to a 4 bolt with splayed bolts if its a 2 bolt. I'm hoping it's a4bolt since its 3970010 block. What would you guys recommend for a crank, rods, and pistons?
