i have a 1979 f150 460 c6 i want to install a toploader 4 speed.
i have a 1979 f250 400 np465 to use as a parts truck.
i have heard that some 6 cyl trucks used an overdrive variant of the top loader will the mounts and driveshaft from one of these trucks work?
thanx for the tip's i want the toploader because its the classic big block and a four speed combo if its a little sluggish than i will just add an extra couple of hundred horsepower :-) to compensate
One problem The OD trannies found in the trucks won't handle the power of a big block if your gonna use it hard.
But the 3spd with OD's can be found behind 302's too. up until 86. My 86 F150 has one. Even though I only have a 302 in mine it's a fun ratio tranny. If it would hold to the big block power it'll be a blast!
The 4 speed OD trans based on the top loader is not as strong as a top loader. The top loader link I listed shows some of the differences.
ZF's will take quite a bit of torque, but I doubt you could shift one very fast.
You enjoy yours because your 302 will rev far enough to overcome the grand canyon between 2nd and 3rd. Us 6 cylinder boys hate that gap, as the six won't wind up far enough to cover the gap.
Of course, you could put in the top loader AND a Gear Vendors OD...that would be quite a set up.
