426 Max Wedge Crank

Here's the way I look at this sort of thing. Even here in the states where parts are somewhat? LOL more plentiful, these cars and parts have been through a LOT. My own experience is an EG. Years ago, I didn't know any better, I put a 273 crank into a 340. It worked "just fine" but I bet a 273 crank is not balanced the same as a 340.

So even if this IS a hemi crank, you are likely going to use some other pistons and or rods, and really, you should have the thing balanced with whatever parts you are going to put in there.

No idea what sort of power you are going to make? Sounds like a fairly stock build if you are even CONSIDERING using that crank.

That is to say, if I could afford a hemi, that is what would be happening, here.
