I got a bellhousing supposedly off of a 351m 4speed to use on my 460. It actually works great clears the 12inch 400 clutch with no problems. But the engine plate does not line up in the starter and lower area bell bolts are fine. The plate is from an auto is this the problem. I asked this in another post also. If I just need the plate for a stick no problem. Reason being I was under the assumption an m bell wouldnt clear a 12 inch clutch without a little help from a grinder.This thing has tons of room. I have the casting number if anyone can tell what it is from so I can get the right plate. It sure would help alot.
Thanks Andy
Andy the bell you have is just like mine, what you need is the standard plate,the starter sits out farther than on the autos because the flywheel is bigger around.I used a dividing plate from an old '70 429 four speed my dad had and it worked perfect except the starter bolt holes. the dial hole itself was in the right place the starter was just rotated a little. you should be able to use the one that came with the bell you got. I hope this helps, oh by the way how did you fix your depth on your piolt bushing?
When I did the manual tranny swap on my 460 I used the 351/400 Belhousing with the 390 flywheel and 11" clutch but to make the input shaft to work we made a 1/2 thick steel plate into a spacer. This set up worked great it made my old 77 350 SWB dually flatdeck into a real truck I never had problems with the 11" clutch slipping and I packed some heavy loads on that deck (6000 to 6800 lbs).
cool kenworth, I took a ford pilot bushing and had a guy turn it down to 1.25" od and drove it into the crank farther I just wondered what others had done to do this. interesting.
I didnt pull the m out yet i was just getting ready with this other bell I borrowed. Because I thought I was gonna have to grind the bell webs to clear the 12" clutch. But that fit great. Hopefully when I get the m out I can use the spacer plate from that. The pilot bushings from a 400m. Im thinking if the input bottoms I may just shorten the shaft. The odd thing is this 460 was already swapped in an f150 4x4 with a c6 and thats the spacer Im trying to use now. Well thanks for the input should know Fri. night if the M's plate will work. I can see spending Saturday in the boneyard instead of putting 460 in lol. Ohh well its all in fun yaeh right.
Ok now you guys got me thinking about this input shaft problem. Do the splines bottom on the bushing or the smooth part of shaft on the crankshaft end. Thanks again.
Are you using a 460 Flywheel with the 400 bellhousing or a 390 flywheel because my cousin tried using the 460 FW and 12 inch clutch and it didn't work. He ended up doing what I did using 390 Flywheel with a 351/400 bellhousing you end up with enough clearance plus you don't have to mount a hydraulic clutch.
We made the 1/2 spacer plate to go between the tranny and Bellhousing it was easier than cutting some of the splines off the input shaft and fooling with pilot shaft.
[updated:LAST EDITED ON 08-Jun-02 AT 02:48 AM (EST)]Thanks Kenworth Im using 390fw with a 12 inch 400 clutch and the m bell. Its going in in about 8 hrs. Glad you answered that its the splines that hit. I have an idea I would like your opinion on since I wont have time to make a spacer plate. What if I shim the tranny back where it bolts onto the bellhousing hhmmmmmmmm. I think itll work since there are no locating dowls and I should be able to get 1/2 an inch out of the mount and driveshafts. Then I can just seal up the gap to keep dirt and water out. If you dont get a chance to reply tonight I'll post my results later.But I think I might be on to something here. Anyone else please feel free to add your thoughts on this.
Thanks you guys rock Andy
Gray don't space the tranny like that! it doesn't have dowels because it uses the big round hole in the middle. you don't have to cut at all on the splines just maybe a little off the bearing retainer for disc clearance to slide. easy compared to making a adapter and just find a guy near you with a lathe and a few minutes to spare and get him to make the bushing to fit into the crank a little farther. easy!
I heard this combo works without any mods: 360 bushing, 390 wheel and 351m/400 bell housing. From what I am told the 360 bushing is exactly the right size. I'd take a gander at one and compare it to what you need. You might get lucky with the 360 bushing.
That is very interesting Wayne, when I was going thru all that the guys at the parts houses came up with the same piolt bushing for 352,360,390,429,460 they said that the book showed the same part 1.875od. and the 302,351 piolt bearing is smaller but not quite enough smaller to fit in the smaller hole on the 385 series engines.
but you and I both know books can be wrong sometimes.
Ok the verdict is in.I used 390fw 400m diaphram clutch and a 351m bell . just put her in yesterday stock 400 bushing no grinding no shims no spacer plate just put it right together with no problems at all.
Thanks guys Andy

Hey Andy what year is your 460? and which 4 speed did you use I assume its a NP435? this is very cool good to hear that you didn't have any problems.
Its a 70's 460. The origional 4spd used in 79. I used the 79 bell a 77 has a different mount for clutch fork but everything clears. The clutch I used was a Luk p,n. 07-050 It fits 77-82 400m and its a 12incH. I used the pilot bush. that came with this set and the 390 flywheel and it all works great. Just one thing to note this clutch is new not remaufactured. Every reman clutch I ordered came as a 3 finger not diaphram. I have about $250 invested in this setup sure beats L&L and its a 12 inch clutch. Good Luck Andy
