Cobra Make, Engine: Classic 427, I purchased it May 2005, the kit was bought in 1991. I'm not sure when it was completed! Installed GMPP Connect & Cruise 376/525 with T-56 S/M 3.55 gears about 2 years ago! 1/4 miles is with old setup!

Is an extra gear and 100# of torque worth $600.00? Into project creep again! The TKO 600 is a 5 sp will handle 600# of torque, the T-56 Magnum is a 6 sp that will handle 700#.

Tremec Magnum Close Ratio 2.66 1.78 1.3 1 0.8 0.62
6500 RPM 50 74 101 132 165 212
3000 RPM 23 34 47 61 76 98

TKO 600 Road Race 2.87 1.89 1.28 1 0.82 n/a
6500 RPM 46 70 103 132 161 n/a
3000 RPM 21 32 48 61 74 n/a

I'm thinking TKO 600 but I'll do a bit more research before I drop the $$!
