Hi, I'm new on here and have a question about a build i am trying to achieve. I currently have a 1969 Ford F-100 Ranger XLT 4x4 with the divorced transfer case and 360 FE block with what i believe is the 4 speed NP-435 tranny. I just got ahold of a true 69 351 Windsor that was rebuilt and mildly built from stock that came out of a 69 Torino. My question is What will i need to do to get my np 435 to bolt up to my 351? ive seen a couple forums talk about 351W bolting up to the np435 but none are black and white really and all talk about the efi windsor blocks not the older blocks. I know ill need a new bellhousing but what eggsactly am i looking for? and what kind of clutch and flexplate and all that good stuff will i need i beilieve its an 11 inch clutch and all but like i said nothin is black and white for me also what about he input shaft? Is there any concerns about this engine swap i need to know? thanks again.

 

You need some education.
1. The 351W is a Ford Small Block engine along with the 302/5.0. It uses the Small Block bellhousing pattern which the Big Six engines (240/300/4.9) also use. Make sure you have a Windsor 351 by counting the bolts holding down the valve covers which, IIRC, should be 5. Another way is to check where the upper radiator hose/thermostat connects to the engine. For a SB, it goes into the intake manifold.
2. The NP-435 trans uses the Ford butterfly pattern just like the T-18 4 speed, so you need a SB pattern bellhousing as mentioned above from 240/300/302 equipped trucks. The 302 was not used in 4wd trucks.
3. You will need engine frame mounts (ND, I forgot the proper term for 4wd equipped trucks) from 77-79 4wd (F-100/250, and 79 F-350) 351M/400 equipped trucks to mount a SB engine.

 

Ford V-8s 221-351W will have (6) valve cover bolts. --351C (335-series Ford engines) will have (8) valve cover bolts.

Pre-'77 model 351Ws will have (16) intake bolts compared to (12) for the 289, 302, 5.0L, post-'76 351W and 5.8L engines.

'69-'76 351Ws will have L-shaped water passages at each end of the heads, where they mate to the intake. '77-up 351W heads will have rectangular water passages.

'69-'76 351W heads will have the larger 18 mm spark plugs. '77-up 351Ws will have the smaller 14 mm spark plugs.

1969 351W head casting numbers should be C9OE-B or C9OE-D. --Other desirable factory stock 351W head casting numbers are D0OE-C, D0OE-G, D0OE-C or D5TE-EB. These head castings will have 60.4cc chambers with 1.84" intake and 1.54" exhaust valves. Valve diameters were decreased in '77-up 351Ws to 1.78"/1.45". The combustion chamber was made even larger, starting in '78, to 69 cc. The casting number for this head is D8OE-AB.

A 1969 351W engine water pump inlet will point towards the right. '70-up water pump inlet will point to the left.

1969 351W engine harmonic balancer/crank pulley will have (3) bolts. '70-up will have (4) bolts.

 

I already know its a true 69 351W guys the casting number is C90E B you dont think i checked that before i bought it? so quit trying to act like im stupid and help me answer my question about the best way to bolt my 4 speed tranny up to it and what all ill need if you dont have any info about it then dont say anything

 

Troncin1 Welcome to and the Bumpside Forum.

You will need a small block bellhousing for the tranny, as the FE is a round top, 302 engine mounts, and for the most part you should be good to go. May be some little things left but those are the biggies.

Whoa....You're gonna need thicker skin or at least some experience in here to understand what and how respondents may reply..... . I don't read anything from ultraranger poignantly questioning your intelligence. We don't know you so chill with the attitude and don't take it so personal.

More than once new FTEers have blazed on the scene and bought what they were told was this or that only to find out later that they were duped by the seller... like buying a 351M but told it was a 351W or a dressed up 360FE but told it was a 390FE.

Respectfully, H/S

 

seems like its happening more frequently now. guys coming in like that, thinking they know everything or acting like they dont know jack$hlt. remember the incident we all had with Clay? lol

troncin1, lighten up. we are just trying to help you understand exactly what you have. if you know everything about it already then why are you asking questions? to put a small-block where an FE was, you need a new bellhousing, new engine mounts, possibly a different clutch and starter. (im not too familiar with what the FE used) and a few other little things like rad hoses and stuff like that.

 

I wasn't attempting to insult your intelligence with my previous reply. I don't know how much you know about the 351W. If you're already aware of what I posted, then sorry for wasting your time.

However, there may be someone else out there, that hasn't said anything but, contemplating a similar swap that would welcome the information.

 

300, 302 or 351w bells will work.

Flywheel, flywheel balance*, clutch size and starter are variable depending on year etc. Bits of info to be found:

*351ws always the same, but it's possible to bolt up the wrong flywheel. Looks like a 164 tooth flywheel and an 11" clutch is where you are headed, more to be found: http://www.rowand.net/Shop/Tech/Ford...Flexplates.htm



Small block Ford flywheel size compare

Earlier bells, before '84, will be for clutch linkage. Check how your linkage works, where the z-bar attaches etc. You will have to duplicate that set up. '85 and up used hydraulic clutches. You can go that way if you wish, just a bit more fiddling in the cab etc. SOME bells will allow you to go either way as they use an external clutch slave and will convert to linkage.

Hope this sheds more light on it, it seems pretty simple but the variations plus changes over the years plus engine series swap always lead to questions.

 

2 X! Prolly more than 1/2 the replies I type I aim not only for the current OP,but also all future folks that will google their problem and end up on one of our threads. I thought Ultra did a great job of informing the "just in case" information. I even REP'd him for it...........
