Boss Crankshaft question

[Ardent]

Forgive me, but I've never seen inside a Boss 302 bottom end. Specifically, I'm looking at the new "Boss" block being offered by FR.

Now, are the main bearing journals the same length as stock in the 4 bolt main Boss block? I want to use a Scat lightweight crank in a 302 on a Boss block, and frankly I don't know if the crank has to be Boss specific, or if they fit those 4 bolts on standard dimension caps.

Thanks folks

The internal dimensions are the same as all other 302's. The main caps are longer, not thicker to accomodate the extra 2 bolts.

Thanks, clears up a lot.
