Ford 392W with 3:11 rear, TKO500/600 ?
I am putting a Ford Motor Sports 392W Crate motor into a Backdraft racing Cobra. It has a 3:11 rear. The engine has 430HP and 450 Torgue. Which TKO should I use a 500 or 600. My concern is not just the torque but the gearing. The 500 and 600 have different 1st gears and the 600 offers 2 different 5th gears.
Thanks Cobrak |
Hi , Iv'e had a tremec TR4250 since they first came out , 3.27 1st
3.54 diff, 25.5 tires , running 351 w, nealy finished a 408 and would prefer the other first gear option now offered . |
Billy Andrews of HRE, one of the best known Cobra builders, suggested I use the TKO600 to mate with my 427 Shelby. Ist gear is 2.87, 2nd is 1.89, 3rd is 1.28, fourth 1 to 1, and I choose the .64 5th gear since I take alot of long trips. Rearend is 3.73. there you have my 2cents. Con
