K1 crank and K1 rods , for a 572 you want a 2.2 crank pin for clearance between the rods and the block .

Lose the M1 dual plane , it's not that great a performer on a 426 it'll be a pig on a 572 .

I also agree ? 85 ??? I'd build it for at least 87 , more like 89.

Pushrod oiling might be a good thing , have the lifter bores bushed and have a 1/8" hole drilled in the bushing.

that's a smallish cam in that size motor for your HP goal I would think .

Contact members Performance Only or Compwedgeracing for the K! pieces and some direction on your build.
