Ok so I got a 1974 ford e100 with a 4.9 six cylinder engine that is not in very good condition pretty worn already, the 1974 comes with a manual transmission, I would like to swap the engine and transmission to an automatic trans and a 302 v8, I have a Ford Rv 1972 e300 that has the 302 and the auto transmission, the Rv is stationary no plan on moving it so I would like to remove that engine and transmission and put it in the 1974 e100 what do I need to do for this swap, what obstacles will I encounter I am new to ford swaps but i have done chevy, pontiac, oldsmobile swaps in the past, any help is greatly appreciated,

 

Well both trucks are from the same generation so you should have everything you need on hand.
The 4.9 six and 302 v8 have significantly different engine mounts that use different frame attachment points. On the newer trucks the V8 mounted directly to the engine cross member while the I6 has additional frame towers bolted/riveted to the rear edge of the crossmember, I don't know if these early trucks are the same but they had to do something to deal with the difference.
Trans cross members are different for manual and auto transmissions too but these should be bolted on and easy enough to move from one truck to the other.
Driveshaft length may be an issue, if your two trucks don't have the same wheelbase you will need to find the correct driveshaft or have one fabricated, but auto transmissions are usually longer than manuals so it may just be a case of having the vans existing driveshaft shortened.

 

Thank you Also I read somewhere that the steering column might need to be swap is this accurate? For the automatic transmission? Since the van was manual transmission

 

Unless you don't care if you have a floor shifter, then yes swapping the column would be required

 

A floor shifter Is fine which transmission does the Ford Rv e300 1972 most thank likely has?

 

302 V8 will have a C4 or a C6 with the probability of a C4 transmission

 

The C6 was the heavy duty trans of it's day and therefore the default for a "1-ton truck" I would think.

 

Amazing! Thank you for all the great advice! Thank you again!

 

I've done engine swaps on a '66 Econoline and on an '81. The '66 was easy, the motor didn't bolt down to the crossmember, just the transmission. The main obstacle was the engine doghouse and it's 40 bolts. Then I brought the motor crane in through the side cargo doors.

On my '81, it was quite a debacle;
On the next generation up from your van and equipped with the 4.9l 300ci six you're gonna have a handful! First, remove the; hood, horizontal radiator support, fan shroud, radiator, grille, and lower wind deflector (below the grille). This wind deflector seems to be easily removable but be careful because there's two nut/bolts in the lower corners where it attaches to the left/right fenders. NOW strip off the air cleaner, carberator, vacuum lines, throttle cable assy. and all frontal belt driven accessories. (Alternator, power steering pump , air pump for the emmissions equipment, water pump & fan, disributor, plug wires, and exhaust pipe at the collector. There may be one or two things I'm forgetting but my project had been four weeks in duration as I could only break from work on Sundays. Now a word on engine cranes, if you can obtain one via borrow or rental your gonna want the lowest height crane obtainable on account of the terribly short clearance there is going to be between the valve cover and the cowling in the moter nacelle. I cannot stress this enough, BE PATIENT this will be a pecker to remove and install. With a conventional height crane I had to resort to raising the rear axle 1 foot and the front end 1 foot to provide adequate clearance for the boom of the crane. This is primarily due to the higher profile of the 300 six in comparison with V-8's Good luck man.
