408 Scat Stroker Kits

The machinist I’m taking my engine to says every balanced kit he’s seen from SCAT needs rebalancing. He may be very fussy I don’t know.
$100 more to get unbalanced parts and let him do it.
($1700)
I will agree with that mine needed balancing full forge scat kit and I paid to have it balanced prior shipping . When my machinist checked it was 35 grms out, got it within 2 grms.
