So it looks like 60mph is about 4000rpm in 3rd then?
I show the tko600 as
2.87
1.89
1.28
1.00
0.64
Rear guessing 4.11?
Bigger carb on top makes it Gonk to 192hp
I wrote my own computer program for dyno and 1/4 mile back starting in the early 1980s, about the same time as Desktop Dyno and others got started. It got named the "WerbyFord Gonkulator" over on fordfe.com a while back, so here I call it the "DeuceCoupe Gonkulator" as it's not just for Fords obviously.
Its not always right but a lot faster and cheaper than hitting the dyno or driving 100 miles to the dragstrip if theyre open.
