[496fe]

Just a coupla thoughts... The close-ratio toploader might not be such a good idea with the amount of torque you have. Usually, the more torque, the wider you want your gears. I had the close-ratio toploader in a previous Cobra and found that first gear was too high, plus I found myself skipping gears while street driving. A lot of 1-2-4 and 1-3-4 and sometimes even 2-4! The FE is quite literally a truck motor and you will get tired of using all the gears. Almost everybody is going with the TKO 600 because of it's wide ratios and unbelievable tall overdrive 5th gear.

Ironically, the best 0-60 times seem to be obtained by "driving out" in first and short-shifting into second.

Driveline losses are a combination of percentage losses (exhaust), which are related to HP, and absolute changes (rear end) that are not functions of HP. My 608 HP at the flywheel turned into 474 HP at the rear wheel, just for comparison sake.
