Darrell's TREMEC Magnum 6-Speed Equipped 1965 Fastback Mustang

Darrell purchased a TREMEC Magnum PerfectFit™ Kit from us about four years ago. It's one of many upgrades he's made to his Fastback. He tells us "even at 8600rpm it shifts as smooth as silk". The TREMEC 6-Speed came with the STX Shifter® which not only shortened the throw considerably, the custom shifter stub puts the shifter exactly where it should be so that the console can be retained.

It may look factory, but the Mustang didn't roll off the factory line able to pull off these numbers. Check out Darrell's 65 on the dyno!

Here's the results of his best run:

He updated his rear gears too, adding a 9" Ford 4.57.

It's easy to see all the upgrades Darrell made here:

Bellhousing, Engine Pan, Suspension, TREMEC Magnum

Driveshaft, TREMEC Magnum, Rear Axle

But in here, everything's still 1965.
