Hi All,

I've got a question for the guys with 427/351W stroker motors. Mine is on it's way, and I need to make a decision on the TKO final drive gearing (.64/.82) so I can order it. I've read the countless threads on the TKO-600 OD gear selection, and while there's been lots of great feedback on lots of different engine/final drive ratio's, I haven't seen anyone chime in specifically with a 427 and whether it lugs or not on the lower (say, 2300) rpm's of the .64 gearing, while cruising down the highway at 70-80mph. I've plugged in all the numbers in several calc's, so here's what I'm looking at (3.55 rear, w/ FFR 17"'s)

.64:
2000 15 22 33 42 65
2500 18 28 41 52 82
3000 22 33 49 63 98


.82:
2500 18 28 41 52 64
3000 22 33 49 63 77
3500 26 39 57 73 89


Thanks,
