351/460 swap in 81 F250 4X4 which PS pump??

Which PS pump is required when doing the 351/460 conversion in a 81 F250 4X4. I have one out of a 76, but there are clearance issues.. Thanx in advance.

The plastic bodied pump with the 2 belt pulley!
Your best bet when doing this swap is to raid all the pulleys and bracketry (if that's a word) from an 83 up till serpentine belt 460.
I have done a handfull of these "460 injections" and found this to be the easiest way out, however, good luck finding a doner!
Make sure you use double belt pulleys for the water pump, power steering set-up or else it WILL squeel!

Well Tell us your clutch issues, I may be able to help. I just did the same conversion. 81 F250 W/351M 4X4 Now with a 460 and 5sp Zf.

The problem I'm having is the disk won't dissengage, I've used the 460 flywheel, 460 clutch assy, with the 351 bellhousing and clutch fork.. I got the motor from a 76 F250, then went 0.30 over with some other goodies.. But I'm stumped on the clutch deal. Is the 460 flywheel suppose to be stepped??
