I have a 1969 N700 with a 361FT 2v. I came across a yard that was selling a 391FT 4v intake and carb that is in very good condition for a fair price. The part number that is stamped on the intake is C5TE 9425 G. Will this bolt up to a 361FT or is it not worth the time? My current carb is needing a rebuild, thought this option would pep it up a bit. FYI, the carb that comes with this manifold is a governed version as is the 2brl that is on mine currently. I know the v4 was an option for the 361FT, just curious if this part number was the one used?

Thank you,

 

The difference between the two was the crank, rods and pistons. Everything else will interchange, intakes included. But I doubt you'll find much difference in this as far as performance, these motors were designed for pulling, not top end performance. You would get the same benefit from just bolting on a larger cfm carb on the two bbl intake.

 

Considering that the carb itself is the only real problem I am having currently, a bigger two bbl might be easiest or just rebuild what I have. I can get the 4 bbl manifold/carb very cheap. Might pick it up just to have. Also, the truck is getting some very poor milage as it is. This could be from the carb needing a rebuild or the whole motor needing a good tune up. I have calculated about 3mpg. The fact that it is only used for plowing snow may be a consideration as well. Its a heavy plow and there is a pretty good pile of ballast in the dump bed.

 

I'd grab it up if the price is right, governor'd 2 bbl carbs are no long available
If your's goes to pot and can't be fixed your done.
You will also notice a bit more power, the 2 bbl carbs starved these engine some in the upper rpm's.

 

A governor's pretty well pointless in a personal vehicle. Put a regular carb on it and a tach. I'd start with a Holley 500 cfm 2 bbl.

 

 

[QUOTE=bhain;17864921]That would have been a mechanical tach driven off the distributor. I'm pretty sure it wouldn't have been electric. I used to rent U-Hauls at a service station in the 70's when I was in high school and remember even then they had mech tachs. I would just install one to keep from over rev-ving it with a non governor carb. The governors were there because most trucks were company vehicles, to keep the connecting rods inside the block when over zealous drivers pushed em to the limits (like I did a few times transferring trucks then LOL) That was my first taste of truck driving that turned into a 41 year stint (so far)

 

 

If you go with the 600 vac secondary your still going to need that 4 bbl intake unless you use a adapter.
What ever you do make sure you have some type of rev limiter.
Most engine damage on these trucks was on the job site, down low in the gears pulling a load on soft ground and the truck pulls up onto some firm ground, suddenly the engine is up against the governor.
Seldom is one looking at the tach when this happens, without a governor or rev limiter to protect the engine, kaboom.
Been there done that, had one with a bad governor go kaboom a couple of times before we figured it out.
