Good luck with Harbor Fright's tech support or trying to specify Hemi/Non Hemi during an online order. I ordered a 69730 non hemi online and specified I only wanted that part number in the comments section of the order. Shipping confirmation e-mail showed they were shipping a 60363 hemi engine. I tried several communications with them, all with the response that the engines and parts were interchangeable, and that the parts numbers reflected different supply vendors making the same engines. When I e-mailed them pics of both style mufflers, air boxes, rocker covers, heads, rocker arms, etc - they didn't reply. Several more e-mails went unanswered. Engine came in as a Hemi 60363, which I traded a buddy for a NIB 69730.
