The Tremec TKO has a reasonable first gear and overdrive, and is great for a road grunt engine Cobra, but I wouldnt consider one for a higher revving smallblock or a big block for a start they have crap ratios, big gaps, and I wouldnt like to put 650bhp through one, but on the other hand the same coy makes the T56, and these are considered to be weak in the mainshaft, so I dare say if you uprate the mainshaft to 30 or 31 spline they are great!

I think I am at the top end of the scale as far as horsepower goes so I dont want to do it twice so the T56 G-force will do it, I had a Jerico on order but commonsense prevailed and I have gone for a synco box as a compromise!
