Kaspa Transmissions Thunderbird Project

The Kapsa Thunderbird was a great car, but a 3 speed petrol eater. It was always pulling left…….To get to next petrol station.

The Car: 64 Ford Thunderbird

390 FE engine

3.7 diff ratio on 275/15 tyres

Approx 15 miles to the gallon

3 speed mx trans

3000rpm @ 100kph

X fordamatic, not only was petrol consumption high, but the 390 FE was rev’n at about 3000 on the motorway. No way to care for the big block engine. The three speed was okay around town, but this daily driver just lacked top end economy and comfort

Economics and fear of un-necessary engine wear was one thing, but it just took something away from the drive and we knew that there was more the T-Bird could offer. With Plenty of power and the potential to be a great town driver and open road cruiser we knew the solution was simple; a 4 speed trans with lock up and endless shift control options. Unfortunately there was no 4 speed to match to the big block FE… problem?

The Solution

Adaptor kit to bolt up to an AODE transmission
