Ok so I bought this 1971 Scout 800B about a year ago with no engine. Everything else is there (t90, Dana 20) but im not sure what motor was in it. I saw some 258 parts in the back of it when I cleaned it out but not sure if thats what was in it. I have a picture of the mounts. Also I bought a amc 304 to replace the hole in the engine compartment. But what im noticing is that the bell housing doesnt match the bolt holes to the tranny. Is that because its amc and not IH? Do I need a bracket to get it to work or a new bell housing? Also the clutch that came with the motor doesnt spline to the tranny either.will I need to move the engine mounts if I want to use this motor? What would be the best fit without doing a lot of modifacations? Not sure if I should ditch the 304 and just use the 6 cyl or what? I would like not to move the mounts because I dont have welding capabilities at this moment. I feel kinda lost in the sauce, so if you could help that would be awesome. Thank you.
Which engine did I have?

I don't have access to a Scout 800a or 800B parts list here at my location. Those are the two versions that May have used the amc 232/258 oem.
But all frame-side mounts for either the 125/196 four cylinder or the 266/304 sv engine will bolt to the frame, some of the original components were riveted on, rivets can be replaced with grade 8 bolts just fine.
The amc 304 engines shares nothing with any IH-produced engine other than it burns air and gasoline! It is a completely different engine and will bolt only to amc-pattern bellhousings and transmission applications. And for the 232/258 there are at least two different bellhousing patterns used.
Ihc only used the amc six cylinder motors to replace their own in-house manufactured six cylinder due to cost and waning popularity of the inline six in the auto industry in the late 60's/70's. It was way too large an engine (physically) to mount in a Scout 800 or Scout II.
The transmission/transfer case support crossmember for these chassis are bolted in place and mounted in various positions depending upon whether the Scout 800 was 2x4, 4x4 and which engine/transmission package was originally ordered by the dealer.
Post a nice pic or two of the actual bellhousing you have currently so that we can identify "which" pattern it is. But a t90/4x4 setup was most commonly used behind either the 232 or a 152/196 four cylinder engine.
Since you are located in roseville...Jeff has many used parts at the new ihon location in Grass Valley just up the hill from ya. I'd suggest ya take a ride to the new digs and discuss options available for ya regarding engines (IH 266/304/345) and bellhousing/transmission combos he has on hand. This would all be bolt-in stuff. Much of the used parts are still located at the Loomis location, maybe he can tell ya what he's got and where with a phone call, and ya'll can make arrangements to hook up where the stuff is located. The new shop phone number is 530.268.0864.

Thank you for your speediness reply. First and fore most my name is chico not that I live there. Hahahah dont worry I get that alot. Ive read alot of threads on here an got alot of info. Still just trying to figure out my next move for an engine though. It doesnt have to be the amc 304 that I have (only paid 100 bucks) already. Just need to know my options and what would be the best route because I dont want a pansy motor. Also dont want to change alotas far as drivetrain just yet. Maybe a t-18 and a dana300 later on when I find a cheap one and earn more money. Ive included some pics that ive taken today. Please let me know what you think. Ive included the bell housing and a pic of the t90 spline.

I would say it was a straight six 232, since the bellhousing isnt clocked for the 152/196 engine. Just my take though, dont know anything to speak of about the 304 engine.

That rig was definitely an amc inline six-powered vehicle oem. The bellhousing in your pic is the amc unit as are the engine supports riveted to the frame which is actually a form of "adapter" IH used when mounting these engines in the 800.
The gemmer steering gear is mounted on the outside of the frame rail, that same gear was used on the sv-powered Scout 800 also. I just completed a rebuild of one of those gears yesterday.
So the easiest engine swap would be any IH sv engine complete with bellhousing and transmission/transfer case. Adjust the crossmember position and bolt it in, using sv engine mounts. The transmission you have now does not have the correct input shaft to mate with an IH sv clutch disc or "stickout", but that could be easily swapped out also.
Also...a t90 would be very marginal in capacity behind any other engine other than what it was originally mounted on, the ratios are badly mis-matched to any of these engine in my opinion and just happened to be something that would fit in the hole.
Or...why not just stick in an amc 232/258??? Edit!! I punched a numeral 6 instead of a numeral 8, the correct displacement of the larger amc engine is 258ci. Nothing wrong with those motors and tons of parts availability for performance apps.
The doghouse and trans tunnel on that particular s800 will work ok for an sv engine install also since it's not a four cylinder setup originally. An sv/800 is significantly different in that regard as compared to a Scout 80 though the bodies appear to be identical.

When we say..."sv", that means an IH-produced 266/204/345, or 392 v8 engine. The Scout 800 was available with the 266 sv in the early version, then the sv option became the 304. Any sv engine/transmission/married transfer case will mount directly into that chassis if it has the oem d44 rear axle, then it has a "centered" differential housing which is used behind a spicer/Dana 20 transfer case.

The amc 304 will bolt to the bellhousing you already have. Amc supplied the mounts and since their rigs used the same mounts on the frame for v8 and 6cyl you May be able to find some mounts that will make the amc 304 bolt in.
So if I bought motor mounts to my amc 304 you think they would fit in the already supplied brackets that are already there? Because I believe that the mounts are amc 232. Does anybody know? I have this stinking motor just sitting and I feel like im not sure which way to go. Scout motors are limited I feel like. The pics of the brackets are already posted up top. The ones that came with the truck. The bell housing is from my 304 I bought, not the one that came with the truck. And if it does work what trannys and t cases would fit? Because the t-90 and Dana 20 I have I dont think would work. Thanks for your help.
