Ok, after some research I am pretty sure that this truck has a NP205 (thats what I am wondering) the shift pattern is 4HI-2HI-N-4LO, and I was under the impression that all 78-79s ran NP205s.

Am i correct in my assumption that this is what I have?

Its currently got a 300 I6 and a 4 speed, but getting ready for a 351W out of a 78 Cougar. that leads me to another question.

Does anybody know if the bellhousing on the 351W will bolt up to the 4 Speed in the F150? the cougar had an auto, C6 if i remember correctly.

The transfer case is fine, just trying to figure out what it is, I would look but its on the other side of the state on the farm.

anyone? thanks

Josh

 

josh. u are right, it is a 205. the 351w will bolt right up to the i6 bell housing. u will need frame mounts from a 351m-400, standard fly wheel 351 or 302 pre 82, 302 truck motor mounts, and a rear sump oil pan and pickup tube,and a pilot bearing for the crank shaft. u will also need the support bracket for the clutch linkage on bell housing.

 

May I add something? You will need the frame mounts from the 1977/79 F100/350 351M/400, the 1980/82's will not work. The 1977/79 351M/400 frame mounts are the same as the 1973/79 302's from the F Series. D7TZ-6028-B R/S & D7TZ-6029-B L/S.


The 1973/79 302 F Series rubber motor mounts are Ford part number: E4TZ-6038-H .. Right & Left are the same.

 

Thanks for the great info guys, i will make sure to write all this down. the motor mount issue made me think of something else. When people do engine swaps, do they most of the time just use stock mounts? I have heard about fluid filled mounts and such, and was just wondering what would be the best.

Is there anything else that I should know before getting to far into the swap this spring? You guys sound pretty knowledgeable, and with this being my first swap, I figured I should get as much info as possible.

I also heard you both talking about frame mounts and motor mounts... are they the same thing, just different name?

Thanks

 

Frame mounts, aka engine perches are the metal stands that bolt to the front crossmember. The rubber motor mounts bolt to them. I'm just a parts dummy, and know little about engine swaps, except parts numbers.

 

thanks for clearing that up, I know what you are talking about now, I guess i had always just grouped those two parts together as one and called them the mount, at least I have a parts guy to steer me along the right path.

Including the parts mentioned above is there anything else that I should need?

 

The only engine swaps I've ever done are the 460 conversions in the 65/79 trucks. After that, I'm clueless, but can furnish parts numbers if I have an idea what the parts come off of, or are going to.

 

alright, well it sounds like I have run into a fountain of knowledge I will defintately be hitting you up for some answers later this spring or summer when I can get back to the farm to get working on it.

I was also wondering about which 4 speed was used in these trucks. like I said before, I cant look for myself, just wondering what was the most common manual transmission for this year, if there was more than one

 

1970's F100/350: Ford 3.03 fully syncro 3 speed; New Process 435 4 speed; Warner T-18 four speed.

 

Its probably answered elsewhere, but how do I tell the difference between the NP435 and the T-18? do they have the same shift pattern?

Also, would you happen to know what the most common axle ratios were for this year in an F150? This kinda sucks being 5 hours from the truck, but i appreciate your help!

 

No crawling under necessary. Look at the shift lever, below the small rubber boot there is a small metal cap that holds the lever in place. The Warner's cap screws on and off, the NP has a cap that twists off with a 1/4 turn. Two pins in the shift tower protrude through the tower, the NP cap locks onto those.


You could also post the trans code off the Rating (VIN) Plate. That code can be decoded and will tell what tranny it is.


If a 4X4, the rear axle could be either a Ford 9 inch, or a Spicer 44. The 9 inch had various ratios ranging from 2.47 to 5.56. The usual ratios are 3.23; 3.70; 3.89; 4.11, but you never can be sure without a tag number from the rear end. (And that is usually missing today). The Spicer had ratios of 3.54/3.70 and 4.10. Add 4.56 to some.

 

I put a 302 in a 79 F-150 4x4 that had a 300 and 4sp originally. It was a pretty simple swap after I found out the towers/perches were the same as 351M/400's. If your rubber motor mounts dont line up with the holes in the towers you might have to loosen up the tranny mount and get a little wiggle room to get the motor to drop in.

 

Thanks for the tips, I will be copying all of this down, it will all really help out a bunch when its time to head back to the farm and get to it
