I recently purchased a 74 highboy with a "390" and the guy has a 390-391 FT motor it turns over and has all the accessories. He told me for $60 I could have it I think it is worth while but I wasn't sure what the interchangeability is between FE's and FT's. If the motor runs well I wouldn't be against putting it in my 74 if I ran into trouble with the "390" or perhaps 360 that is in it now. Any help and personal oppinions would be appreciated.

 

For $60 I'd take it and part it out on ebay or CL. Keep the forged crank if in fact it has one. Maybe the block depending on status. the rest is of little use in a 1/2 ton IMO

 

So if the FT motor runs good you don't think it would make a good motor for a 4x4 3/4 ton?

 

79, by all means, get it. Lots of guys want the blocks, and the 361 and 391 FT both have a forged crank, which lotsa guys also want. Yeah, you could put one in a 3/4 ton, it'd be fine. They will be a few details you'll have to fuss with, but nothing unsolveable.



Check to see if he has the tranny and bell from behind the FT. Lots of the FTs had a very nice Clark 280 series 5 speed behind them, and you wouldn't want to miss out if he has that as well. DinosaurFan

 

It does in fact still have the 5spd behind it with parking brake drum and a pto, if he will part with that for $100 or less I'll pick that up too. Do I need the bell to put the FT in my truck, I thought they shared the same bell pattern?

 

Different clutch, the crank has a bigger snout, the list goes on.

Bottom line is that the FT is a truck engine for bigger trucks. If all you want to do is putz around the farm and haul junk, it will live forever.

The FT engine does have a good block, and some have had the crank snout cut down and re-keyed for racing. The heads and intake are not what anyone call "performance" items. LOL

 

79, the FE & FT share the same bell pattern, but the bells don't all have the same pattern on the tranny side. The FT bell will have a pattern to match the Clark 280 series on the trans side of it, the FE bell fits toploaders and stuff like the NP435 and T18 & 19 DinosaurFan

 

The FT engines use a U shaped front motor mount bracket that bolts to the front of the block to mount the engine to the front crossmember.

The rubber mounts are donut shaped and are in the center, one above the crossmember, one below.

330 H/D, 361 and 391 FT engines do not have provisions on the right/left side of the block for motor mounts.

How are you going to mount that FT engine into a 1967 and later 4WD pickup?
---------------------------------------------------------------------------
There are FOUR FT engines: 330 M/D; 330 H/D; 361; 391.

The 1964/67 330 M/D uses a 352 FE crankshaft, the 1968/72 330 M/D uses a 360 crankshaft.

The same crankshaft was used in the 330 H/D and 361, the 391 crankshaft is different.

Use with: New Process 435 4 speed / New Process 541 & 542 5 speeds / Warner T-19 4 speed / Clark 250, 260 & 280 5 speeds / Clark 300 5 speed.

The only FE engine factory installed in 1968/76 F100/250 4WD's was the 360 2V.

No 4WD ever came from the factory with a 390.

 

fab up a motor plate is what i would do. a few extra gaskets and some longer bolts.

just cuz the factory didnt put it somewhere doesnt mean it wont go there.

 

Go ahead and install that boat anchor of a 391 4V (if that's really what it is) FT engine into a 1974 F250 4WD.

Before you do, better replace the front springs, cuz what's in there now was not designed to handle the extra weight.

The front drum brakes won't like the extra weight either.

Most FT engines are 330 M/D 2V's. Most peeps do not know one from another, and the block casting numbers are useless to ID what it is.

 

Bill I hate to disagree with you but FT's do have side motor mount bolt holes. Also the weight difference is'nt that severe. The main difference is that the Heavy Duty blocks used a bigger diameter oil pump drive and had to be sleeved to use a FE distributor.

im not positive, but keep in note the exaust manifolds exit in the middle of the engine,so i'm not sure if they will interfer with the mounts(perches).the oil pan and pick-up tube is worth saving.the flywheel and clutch is way overkill for what your using it on.i dont know for sure if a FE flywheel will bolt to the FT ,but if it does then that would be the way to go.the FT is pretty heavy and unnessary even for my F350.you might have to change the oil filter housing because it is a verticle instead of the horisontal,or change to a different filter number dummy knows the # of the filter.all in all it has good parts on it to build a nice FE.i think one of those FT's has the same stroke as a 390 but im not positive.

 

oh yeah,if you use a FE trans,make sure the pilot bearing in the FT machtes the same as the pilot bushing on the FE.the input shaft is bigger in diameter on the FT.so one other thing is to make sure of the end of the FE VS the FT pilots are the same.i think i made sense,i hope.yall have a good one

 

The 1973/78 330 M/D (which uses a unique block, not shared with any other FT engine) has side motor mount holes because Ford installed this engine into F350's they built especially for U-Haul.

The other FT blocks...at least the ones I've seen, have no provisions for side mounted motor mounts.

 

the 330 i had ,had the same oil pump drive,dist etc as my 360.
