i posted two days ago about what the tags and casting numbers on my driveline mean i was just wondering if any one had any idea or if you could direct me to some books or another website that might be able to help me out with identification of these parts   thanks  

Well, it seems you have a great project goin there Fumbles. You say that you have a 351M, Well that "M" stands for"Modified", which is one of 3 different types of 351's. You will need to specify that "M" to your parts dealer every time you go looking for parts. The other 2 351's are the "Cleaveland" and the "Windsor". The main differences in these 3 motors is internal....heads, cam, crank, pistons, rods....etc. As far as I know, the 351 is a stout and usualy stong motor. It is very popular for it is easy to work on and new as well as used parts are everywhere. They were used in cars and trucks. As for torque and h.p., you may have to look further into the internet for answers. Factory torque and h.p. may be found in a Chilton Repair Manual, which are usually available at most public librarys or at your local parts store. Is it a good motor? Well thats a matter of opinion, and how much abuse it has endured. A well maintained 351 should last 150,000 to 250,000 miles before major overhaul.

As for the tranny, I dont recognise the numbers, but then trannys are not my specialty. Is it an automatic or manual?

NP-205.......New Process 205, Made by the Borg-Warner company. Try digging in past issued of Pedersons 4Wheel &Off road to find info on your transfer case, or maybe a letter or e-mail asking for references. The "f" stands for Ford, there were versions of this transfer case made for Ford, Dodge, and Chevy, all slightly different.

More than likely you have a standard Ford 9inch rear end with matching 350 gears. My 1980 F-150 has the same gears.  What does 350 gears mean? Well, 3.50 turns of the drive shaft for 1 turn of the axle. These are a good all around gear, and easy to find replacement ones if you should ever have any problems.

I hope you find this usefull, Good luck and Happy Trails to you too.

thanks for the info it is quite helpful my tranny is an auto and now that i have this info i can go a little further and find out what i might want to do to the truck . you said the rear end is probably a 9 inch is there any way that i could find out for sure and if it is would you be able to tell me how hard it might be to put a locker in  i was looking at a detroit and wasnt sure which one i might go for. also what rim tire combo and lift would i want to go for  this is my daily driver but i want it to be pretty capable off road im not going to be doing any major rock crawling or anything but i want to be able to tackle some pretty rough trails   thanks again

The Ford 9 inch is the most common Ford rear end. Lockers are available for them, but thay are out of my league. Contact your local off road store or web site for further details. Tires? Well, I would get an all terrain tire if you are going to use the truck as a daily driver. they generaly have a better warranty and will last longer than mud tires. My first a/t tires were $90 each. They were cheep, and that let me experiment while under a budjet. If you have alot of cash, than get whatever you want as for a combo. If you are working under a budjet, start with 31X10.5 R15 tires, they will fit stock hight and should look good. Chrome wheels look great but they dont like off road abuse, steel wheels are tough and if you bend a bead, you can bend it back with a hammer to get you home. When you have the cash, go for a body lift. they are cheep, and wont rise your center of gravity too much. A 3 inch lift will let 33 inch tires fit, maybe 35's. If by then you find yourself off-roading more and feel the need for a suspension lift you will know if it is worth the cash. I only have time to off road about once a month so I go as cheep as pasable without comprimising safty.
