For pulling power the Ford 300 cid inline 6 cylinder was a BEAST. 170 h.p. and 283 ft lb of torque and 3800 rpm, and they could run much higher rpm. 4" bore and 3.98" stroke made it an engine with a wide torque range. It didn't take long for a few guys in the town I lived in to take them out of wrecks and build them up and put them in cars. Real sleepers in the 1/8 mile drag races; the V-8s would be burning the tires off at the hole shot and the 300 inline 6 would be screaming down the track way out ahead. In the quarter mile the V-8 would normally catch and pass them, but in the 1/8 mile run, the 300 was darned near unbeatable.
As already mentioned the old Dodge slant 6 was another engine that was hard to beat back then, too. And it was offered in a performance package from Chrysler that boosted h.p. to 200 h.p. And it also had gobs of torque like the Ford 300.
High performance parts were available for both the Ford 300 and the Chrysler 225 Slant Six. And they were used a lot, too. Nothing like embarrassing a big V-8 in the 'red light to red light' racing common back then!
And more news on the Chrysler Slant Six. It might be brought back into production by Fiat Chrysler! Less moving parts than a V-6 and power comparable to a V-8.
The Hemi V8 engine returned in 2003. Could the Slant-6 be next?
Fan and insider website Allpar.com reports
that Fiat-Chrysler is secretly working on a new inline-6-cylinder to
replace its current line of V6 motors in several vehicles.
Straight-sixes are typically smoother and use fewer parts than a V6 of
similar displacement, but are longer and can be harder to package in an
engine bay. The only ones currently available in the U.S. are found in
BMWs, Mercedes-Benzes and some heavy diesel trucks.
Then-Chrysler
Corporation’s legendary “G-engine” line was first introduced in 1959,
and got its Slant-6 nickname from the 30-degree tilt to its cylinder
bank. This allowed for lower hood designs and repositioning of some
components to reduce its overall length. The last vehicle it offered
with it in the U.S. was the 1987 Dodge Ram pickup, but the automaker
continued to sell Jeeps powered by a different inline-6 that it
inherited from its takeover of American Motors until 2006.
The new 3.0-liter engine is expected to be turbocharged to deliver as much power as the automaker’s 5.7-liter V8. Sources suggest to Allpar.com that it could debut in the upcoming rebooted Jeep Wagoneer,
but may also be used in the new Dodge Challenger, Dodge Charger and Ram
1500 pickup. Small, closely-spaced cylinder bores and a low-profile
head may be used to create as compact of a unit as possible.

According to the Chrysler dealer I talked to they may quit making challenger, charger line. The 300 is done this year and they say Chrysler is pulling the plug on sedans of any kind. More money in suvs and pickups. Our haywagon had a 300 six and it was a great engine. A friend of mine's dad had a 292 six in a chevy pickup and it was pretty waspy. Jeeps inline was a pretty good motor and we had a few late model ones that were injected and that really made them more responsive.
I have zero problems with people who actually need/use SUVs - but the vast majority of them that look like a stylized athletic shoe that never tow anything, haul anything, nor go anywhere near a mud puddle annoy me. That market is FAR better served by either cars or minivans.

As for jeeps it depends what you are using them for. I had a good friend that had a 1960 cj, it was fun but 60 was approaching top speed. I spend around 6 hours a day in my jeep, I like a heater that works and ac and power steering. Would I remove the top and get it wet, NO, it has electrical issues already. I just wish I could buy a new one, they quit making ones like I have so I am hoping this one stays together until I can retire.
From what Ive read, modern refinement in fuel delivery, variable valve timing and sophisticated computerised ignition can get alot out of a smaller engine. Even the blocks and bottom ends are becoming lighter and stronger. I had a Ford 300cid six and two Chrysler slant sixes. Modern touches would have put a serious shine on them.
Pretty much what Early said. I don't like computerized engines, but even I'll admit that when they work, they work well. Better metallurgy and better machine tools have added a lot, plus better understanding of the entire ICE physics aids better (computer aided) design. I'd like to see GM bring back their big block V6 line with modern upgrades, such an engine would be downright awesome. The old AMC/Jeep straight 6 would be another one - pretty indestructible even with heavy abuse by all accounts.

No matter what engine just be sure the true Jeeps keep the straight front axle.
Yep. If I were to actually build my dream with the GMC V6, it might need a couple of extra leaves added to the front springs, and would definitely need a straight axle. That V6 outweighs a 454 if I remember correctly.

I have always liked big V-8s for fast cars and boats and although I cant prove it I always thought for sheer pulling power and low end torque a inline 4, 5, or 8 was better. In 67 I ordered a new Bronco with the 170 engine, 3 on the tree, 4:10 axles with posi in both. In 68 I needed more power to pull my boat and travel trailer so i ordered a new in crate Ford 300 inch 6 with bell housing flywheel, clutch and a new New Process NP 435 4 speed **** that had a 4:90 first gear, I built new engine mounts and installed the big 6, it was to tall to close the hood so I built a 4" high air scoop, added a Clifford 4 barrel manifold and headers, Since the Bronco had coil springs on the front I got a set of Ford F-150 springs, added duel shocks all the way around. Other additions were duel oil filters and oil cooler from a D-18 Beechcraft, the NP-435 had a 6 bolt PTO so I put a Koenig 8000 lb PTO winch on it and Gates 10 x 15 Golden Commandos tires, the largest I could get at the time To this day I'm sorry I ever sold it, I still think it was the best 4 WD I ever owned.

That sounds awesome, do you have a picture of it?
