6.4 block bored to 4.125 (.035 over)
Crank offset ground to 2.0 journals and 3.845 stroke $300
Chevy 6.2 H beam SCAT rods (I already have this set but for the sake of discussion) $662
1.135 chevy 400 std bore off the shelf flat tops cut my own valve notch racetec $663 probably could find a cheaper brand with a little digging
Balance $200

I can't find a stroker kit for much less than $3000, heck I can barely find drop in piston and rods for $2000 and it still needs the block bored and all the other little stuff either way.

It would be just under 11.5 compression and 411 CID all forged


On the piston cutting for valves could be a problem, head thickness , most race type pistons are thicker at the valve notch area on the underside ,,top ring location. Rod width on the big end ,other than those questions I like it .
