Brent's listing in the classified section. He did well by me. We used a TKO 500 in my sons 67 Gal and the .64 o.d. worked well with 3:50 rear gear with 428-445hp/504ft.lbs. If your running considerably less torque than that you might want to go to something like a 3:89 rear gear or use the road race .82 version. The tko 500 first gear is a little low but the 600 is higher and as Goldylocks said should be just right. Mike
