I6 Engine Swap -Need Advice!
Here's the deal:
I've got an all-original 1970 F100, with a 300 I6 and a 3-speed automatic.
Engine has no compression anymore, so I am going to pull it and slowly rebuild it.
This is my daily driver, so in the meantime an old-timer has gifted me an 85 F150 with an I6 (4 speed manual tranny).
Both are carbeurated. His comes with bonus power brakes, power steering and proper air filter housing.
I am about to swap the engines, but I have no experience on jobs this large. This is my first truck restoration!
I could use all the advice anyone has to offer, but I have a few worries in particular that need addressing:
Will the bellhousings match up, or will there be issues due to the engine years/tranny types?
Are the motor mounts the same for these years of I6?
What needs to be taken to swap the power brakes to my truck (I currently have drums all around)?
What needs to be taken to swap the power steering to my truck?
Any other major issues of compatibility that i need to worry about?
Thanks for reading folks!

Sorry other than the engine there is not much usable for your 70. Starting in 80 many changes were made. Engine fitment should work, maybe throw out bearing will have to be pulled from crankshaft. You need a 73-79 donor for steering and brake upgrades.

Yup, steering is on the wrong side of the front axle. You will need to use the older oil pan, oil pick up, distributor, carb, maybe manifold, and engine mounts. Your old stuff will bolt up to the bare block.
You may need to knock out a plug to put the dipstick tube in as well.

Correct. It should be a drop in just put your accessories on it alt bracket alt carb dist. water pump pulley motor mounts flex plate etc. I'm pretty sure the Oil pan off the 85 will work in your 70 it may not be ideal (Oil will drain on to cross member) but it should fit.

[QUOTE=F***100;16606802]Wonderful! Some dipstick welded the dipstick tube -must have cross-threaded it. So I may have need of that oil pan[/QUOT
If I recall correctly the tube just pushes in.

Even with the "right" oil pan, it's going to get oil all over the crossmember when you change the oil. My '69 F100 has its stock 240 with its stock oil pan. The drain plug is positioned where it will dump oil on the crossmember.
When I change the oil, I take a piece of cardboard, bend it in half so there's a Vee in the center and use it as a trough/gutter to route the oil from the drain to a catch pan and not splash oil all over the crossmember and steering linkage.
