IH Scout 4 cyl engine

Mo in NE tex · Jun 9, 2017

Subject came up this morn in Coffee Shop about IH and others back in the day making 4 cyl engine from V8's. Most used same parts thru out, the question was did the Scout use the same crank in the 4 as was in the V8? If so, what did they use on the unused journals to stop oil flow. Just one of those questions that gets you to thinking, since they used the same heads, water pumps etc.

Different crank. A v 8 crank won't fire right.

I remember the Scout engines. Seems there were others that did the same, but can't remember which ones.

Tempest maybe? Any others come to mind?

Anybody have a scout with a 4 cyl engine

Butch(OH) · Jun 9, 2017

Crankshaft was different to accommodate both the firing order and having one rod per journal. Dad had a Scout back when they first came out and later a 1/2 ton IHC pick up, about a 1964 model, that had that engine. Think it is gutless in the Scout you should had same in a pick up truck, LOL. Dad also had a 61 Tempest with the slant 4 , he must have had a thing for half V-8s?

Scouts came with four different four-cylinder engines. 1960 had a tiny Austin A55 engine rated at 49 max horsepower. 1961 half a 304 V8 was offered as a 152 c.i. four-banger with 93 max HP. Same bore and stroke as the 304 V8 but had its own crank. Same engine also offered with a turbocharger with 111 max HP. In 1966, half a 392 V8 was offered as a 196 c.i. four-banger with 111 max HP.

Pontiac four-cylinder was half a 389 V8. Came in standard or "Indy" version. The latter with high compression and 120 max HP. That was 194 c.i. and an aluminum 215 c.i. V8 was also offered that weighed less then the four cylinder with 155 max. HP. A turbo version also came out.

ep, 90-180-270-180 degrees between pulses instead of 180-180-180-180 would make a real shaker!

I did not own one, but worked for a man who had one. What a POS!!! The only thing it had going for it was the 4 wheel drive.

Pontiac was half a 305 i believe 2.5 L, 152 cid. I have one i don't need. Under workbench, have not seen for awhile.
Maybe there were 2. This one was used in Chev Citation and S10 pickups. Not sure of block design. I guess I need to look at it. Iron Duke. Deere cast these blocks for awhile in waterloo when they couldn't sell tractors in farm crisis.

JDEM · Jun 9, 2017

No the Pontiac four was not "half a 305." The 305 was not even invented yet. 305 was never a Pontiac engine either. The four in a Pontiac Tempest was half a 389 Pontiac-only V8. It was 194.5 cubic inches. 4.06" bore X 3.75" stroke, just like the 389. Came in a low compression version with manual trans or high-compression with an automatic trans. Retail price of a four-cylinder Tempest in 1961 was $2800. 2000 were built with an all-aluminum Buick 215 c.i. V8 ($216 extra). A high-performance four was also available with a four-barrel carb and rated at 155 HP which is the same as the Buick V8.

I had one and had the pan off once. The crank is two up and two down like any four cylinder. The mains were the same as the V8s. The front, IIRC, offset was curved back to make the narrower journal. Gutless? What do you guys want, a seven second quarter mile? I pull-started a diesel loader tractor on a gravel road once. I dragged it along with one rear going forward and the other spinning backward. Also had one with 345 and Carter thermoquad. The four was a lot better for winter driving.

Mike(NEOhio) · Jun 9, 2017

The only real differences were the crank and cam.

Gambles · Jun 9, 2017

I once saw this same 4-cyl engine on a Sullair (IIRC) industrial compressor.

Dean · Jun 9, 2017

Bingo, JDEM.

Pontiac offered the 1/2 389, 45 degree 4 cylinder engine in the early Tempest with "4 of everything," i.e., 4 BBL carburetor, 4 speed transmission, and 4 cylinders. I saw one once at a local service station getting an oil change.

I miss the innovation once common in the 1950s and 1960s when the car divisions operated mostly independently.

Yes Ivan Mya daily (go to the coffee shop is a 1979 4 cyl truck style and have several more.

Different crank ,, odd thing is they even used the v8 distributor cap, just plugged ever other hole. Have several engines laying around and have built a few. Pistons rods and most other internals will fit.

JDEM · Jun 9, 2017

Maybe they should of called it the 4-4-4 and beat Oldsmobile with the idea by a few years. 4-4-2 for "four-barrel", "four speed" and "dual exhaust."

I had one of those early Tempests with the transmission in back, with a 326 V8. I blew the engine and could not find a replacement. It was a special-built engine because the end of the crankshaft was designed to mate with the rear transaxle or pilot shaft (I forget). That was a 1963 with the cast-iron 326 V8 instead of the aluminum 215 V8.

Dean · Jun 9, 2017

Interesting, as was the so-called rope drive.

Again, I miss the once divisional competitive innovation.

Back in the '60's and '70's GMC had a huge V-12 gasoline that was based off of two V-6 engines and if my memory is correct, had two distributors. I think from memory was 700+ cubic inches and the cranks may have been welded together to form one huge crank. Used it in 2.5 ton trucks and the sort as I recall.

After posting about the GMC V12 above, I googled and found a Farmall puller with one in it. I guess that makes this string tractor related.

My nephew has Dad's old 4 cylinder 1965 Scout.

Brendon-KS · Jun 10, 2017

There's a 1961 model setting in my shed right now with the original 152 "slant 4".

JDEM · Jun 10, 2017

No welds. Just one long crankshaft.

Mark - IN. · Jun 10, 2017

Thanks. I just remember that the engine was massive. Think was pretty low HP but had enough torque to move a mountain. I only ever saw one such V-12 back in the '70's on a Saturday in the summer while working at a gas station as a kid. Was in a cab-over GMC that was tipped up getting its air conditioning recharged. Was massive. As I recall it stuck out further than the cab when the cab was down. Maybe not, but was massive.
