scout 80 eng swap /drive train

[curlylobo]

Considering purchase of 65 Scout 80 (4 cyl, folding windshield.)
how hard is it to swap from 152 to 196, 4 cyl eng????
How weak is the drive line for someone who will only go offroading rarely. I have read that other cars also use the warn overdrive that was an option on the Scout. Anyone know which cars to look for when I hunt this unit??????
Tks

It isn't that difficult if you've got a picker and you've done engine swaps before. You need a 196 from an 800, not from a Scout II for the correct engine clocking. Better still if you can get the 4spd from the same donor 800 and swap both in. Space between the valve cover and the firewall gets a bit tight. Access to some of the bell bolts through the trans tunnel gets a bit ridiculous, requiring some creativity. The drive train is plenty stout for light off-roading. These things were built to go damn near anywhere...very slowly. As long as you keep the tire size reasonable. A '65 probably has a tapered Dana 44 in the rear and the Dana 27 up front. The 27 can't handle big tires. Even with the bigger 4 cylinder, you won't have the power to turn big tires anyway, so just limit your size to 30 inches and you'll be fine.

I have done swaps in the past, and have the equipment and space. Just never on a 4x4, although I have maintained them
in the same spirit, it seems Ford 302 would be a good candidate for the same useage. Yes??no??

I'm sure it's been done. The 800 196 and matching 4spd is pretty much all direct bolt in. Anything else even IH v8's, will require varying degrees of fabrication and adapting. Being its a 4x4, other make engines will lead to additional challenges in getting that power transmitted to both the rear and front wheels when desired. The Scout has passenger drop front axles. Most Ford 4x4 stuff is driver drop. The Scout 80 trans tunnel is very tight, requiring a "pancake" bellhousing. Standard dimension bells won't fit without significant tin work. One must really do their homework, consider all the angles and be thinking several steps ahead if the goal is to go with some other engine block for power in a Scout 80 4x4.

Someone mentioned that the optional warn overdrive could be sourced from other makes of salvage yard cars. Anyone know which ones?????

The warn od came in a few flavors. The main difference is the bull gear specifics that your t18 transfer/ t-90 transmission has. The one that will fit an oem Scout 80 has a 6 spline transmission output shaft and bull gear has 29 teeth. So you need the main od unit with the 6 spline-29 tooth bowl gear.

There was also a front or rear shifter rod option. This won't really matter much as the linkage will transition either way.

Iirc the original warn model number for that unit was a m33-29 and the shift rod comes out the front (did on mine). Not to be confused with an automotive od (warner gear -similar name but no connection) used on 50s fords and such that someone once made an adaptor for, but that's not the way to go.
