Will any stock 5 speed hold up to a built 351?
Apparently the 302's all came with the M5OD, what did the 351's have... was this the M5R2, or did they use the M5OD as well?
If all the transmissions are the same then dropping a 351 in a 302 or 300 shell shouldn't be that hard?
The engine would be .030 over, alu cyl heads (whatever I can pick up used, FMS/Edelbrock/AFR), Hydraulic roller cam, longtubes, megasquirt EFI, stock duraspark... Probably put down around 350 hp or so.
If this isn't possible I'm looking at the tremec T600, and all the grief that would entail...

ZF is the manufacturer, the transmission is either an S542 or an S547 in later years. It was available in a diesel version, big block gas version and a version for the small block. You would need the one for the small block. Ford never put a manual transmission behind the 351 in the F150's (ZF's website lists the F150 as having a ZF in 88 only, but I'm sure they are impossible to find).

ZF would be the stoutest, but the gearing may not be ideal depensing on what you're looking to do with the truck. i mean, if you're gonna use the truck as a TRUCK, it's great. with that built engine, though, it sounds like you're going for speed, yes? the ZF has a granny 1st gear that would make your life tough, although it can get off the line decently well starting out in second (for a truck).

Me personally I would not even want to think about an M5R2 (correct name for the "M5OD") behind even a stock 351. But you will have to get the engine management from whatever F-250 or above to run the 351 without expecting to have an automatic there to control too. And I am not sure what that does to smog compliance...
The M5R1 was what they put in Rangers.
I think I remember that ZF is a German company..

The M5OD and M5R2 are the same thing.
An M5 would hold up to a stock 351 but not a modified one.
The M5 didn't fall within the specs of a 351's tq being rated at 330ft-lbs. So it was never behind the 351. I duno why they never really put a 351/zf/f150 together.

Actually, I'm pretty sure it did handle the torque specs. It was the transmission Ford chose to put in the Thunderbird SC's just because it would handle the high torque. And the first years of the SC put out 315 ft lb, and the later years were 330 ft lb. But at the same time, they were only ok in that application too. But people have them in built SC's running in the low 13s, maybe high 12s. So they might take it, at least for a while...

A 3200-3300 or so lb thunderbird is different than a 5000-6200lb truck (including payload). The added weight of the vehicle is a factor here.
Sure, the ZF would of been nice to have...but it's really not very hard to put one in lol. They couldn't of made it any easier. A 5.8/ZF swap from a 5.0/M5 is probably one of the easiest swaps out there.
