you ran it a dragway 42 didn't you? i was there. car looks really clean dude
big shot dyno is a great shop as far as ive heard.
i had my car out there but i didn't run it. it was my first time being a d42. i think i will be running my 01 gt next week.
i think my buddy has a couple videos of you running if you'd like to see em.

The 99/01 Cobra and Mach 1 have better heads/intake than a B head Cobra(96-98) and the Mach has a better powerband than the 99/01 Cobra due to the different cams. Both cars make more power in stock form than a B head Cobra.
On what planet is 13.7 slow for a stock '96-'98 Cobra? I agree there's more left on the table with that 60ft, but 13.7 as a base run is way better than average....especially in a car with the stock 3.27 gears.

A bolt on 2v is going to be faster than a stock 96-98 4V with drivers being equal. Your time is very good for a stock 4V despite what four six said.

Yes and your 2V had more rwtq(many do in stock form too) than a stock 4V which is why it tends to get down the 1/4 quicker. The B head 4V has less torque in stock form and the same rwhp as your old 2V.
However, the 4V relies on the higher breathing hp to get the job done. That is why the C head Cobra ran 13.4-13.5's in stock form as they had more rwtq and rwhp. In a way Torque= how much work and engine can do and HP= how fast it can do it.

Its not necessarily that the ealy 4V's made less torque that the later PI headed 2V's (they make slightly more actually) its that said torque comes on somewhat later in the power band by comparison. A few guys have experimented with modifying the IMRC motors to allow the plates to open a little later on in the power band that they're set up from the factory (approx 4,000-4,200RPM). This is said to improve torque, throttle response and in town fuel economy greatly accross the board with the early B-headed DOHC engines.
I might consider looking into that before going too drastic with the rear gears. Especially if this Mustang is going to spend any time on the highway and is expected to retain any sort of fuel economy.
