400 block is it cheaper to buy stroker kit

Unless you're using insano heavy parts, no BBM crank is going to need mallory, so a balance job should be a couple hundred bucks or so.

What's the purpose of this engine, that's kinda important in determining what parts you need? S/F....Ken M

He's putting a 440 crank into a 400 block.

Don't forget about turning and polishing. The 440 crank has to be turned down to fit in the 400 block. Plus you're not using the same rods that came with that factory crankshaft. Nor are you using the factory pistons. Lots of weight difference with those two things involved.
