i have had many motors built over the years, when builders told me 3 month turn around it took 6. i recently had 2 top ends ported by kevin herr. 1 week turn around. sent them on mondays they were back in the mail next mon. no bullshit. cylinders fit perfect in a large usps flat rate box, 14.00 with room for packing. cranks fit perfect in a smaller flat rate box, 11.00. with packing. both with tracking.
