OP:
Why aren't you going with a factory longblock?? There are guys running a nitrous plate setup just aft of the throttle body with a smaller pulley and Diablo tuner running 9's in a factory weighted (~4500#) hellcat! You don't really need any more stroke; just add boost. The factory stuff is pretty dang stout and for the price of a longblock, you might be wasting money going a different route.
I bought a bare block before the short blocks were available. I also have a bunch of different Gen III internal parts and figure I could get something to work.
Here is what I have:
New factory 6.4 crank
New Factory Hellcat rods and Pistons
Manley 300m 6.125 2" journal connecting rods
Manley 4.09 bore platinum series pistons
Good stuff but it's kind of like legos that don't match lol.
Figure whatever way I go I will have to buy something.
