V-8 pairs that share displacements but not manufacturers | Hagerty Media

If you're an AMC owner and get tired of questions like "Why did they install a Chevy engine in an AMC?", this story is for you. Ditto Studebaker folks who must deal with people asking about the Ford 289 in their Lark.

What about the 289 V8 in the 1936 & 1937 Cord?

For years I assumed that the 304 V8 in International Harvester Scouts was the AMC engine of the same displacement. It wasn't, though IH did use the AMC 401 for a couple years. AMC and Mopar both made 360s too, which became really confusing once Chrysler bought AMC. For a while they made both, the AMC engine being in Jeeps and the Mopar being in other Chrysler products.

CamJam, speaking of 401's there was also the great 401 Buick V8 that deserves mention. Ford also made a 360 c.i. truck motor in the '70's.

Studebaker's biggest factory V8 was the R3, called "304.5" because they'd finally had enough of being confused with other people's engines!

My Grandpa built an AMC 327 for a Willys project truck. It ran beautifully but was always interesting to get parts for. Often the parts guys at the store would slip us Chevy 327 parts thinking they knew better, because Chevy is the one who made the 327. hahaha. I last rebuild that engine about 20 years ago and added Holley 2V Projection to it and dual exhaust. Oh it sounds awesome, so much better than a lot of things on the road today. Sadly, I sold it all some years back. It was a bit hard to let go of, but time. If I ever have another opportunity to own one, I think I'd like it to be in either a Rebel or Ambassador.

Great article diego, but wasn’t the roadrunner 383 335 hp?

The RR didn't feature the highest hp for the 383.

@Topblissgt, 1959 Dodge with the Super D-500.

There also was a 383 with 2x4 in 1962 that put out 343 horsepower, I believe.

Chevy 302 cid (69 Camaro) and Ford 302; Ford and Dodge both made a 360 cid engine - 70s trucks. AMC and Ford made their own 360 and 390 cubic inch engines, Cadillac had a 390 engine. Oldsmobile had a 330 cid engine in mid-1960s while Ford had a gasoline 330 cid engine in a 1965 F-750. Buick also had a 340 cid engine in 1966 and MOPAR had the famous 340. Chevy 307 in late 1960s vehicles and Oldsmobile 307 in 1980-85 Buick Riviera/Oldsmobile Toronado. Chrysler had a 400 cid engine — 76 Charger, Chevy had a small block 400 cid engine - 78 Blazer, Pontiac 400 in 67 GTO and Ford had the 400 cid engine referred to as “Modified” or 400M - 77 F-250. Both Ford and Pontiac made a 428 CID engine. The article discusses the 383 Chrysler engine, but doesn’t mention the 383 Marauder engine by Mercury-Edsel-Lincoln in the late 1950s. Jeep 304 (CJs) and International 304 (Scouts).

Don't quite understand your grammar, sorry! Are you saying the Jeep 304 was a Mercury engine? I have a friend with 304 AMC Jeep and I thought it was a Chevy engine!

That 304 is aaaall AMC....  Distributor's in the front, not behind the carburetor like Chevrolet's. Nice engine, especially in a CJ.

Ah yes, I remember the time I went to the auto parts store to pick up an oil filter for my 1965 Jeep Wagoneer, equipped with the mighty "Vigilante" 327 (AMC) V8. Probably should have known something was up when the guy behind the counter immediately grabbed the filter off the shelf without looking it up. The filter screwed on perfectly, but when I started the engine, it immediately started pumping fresh oil onto the ground. Turns out the fitting was the same, but the gasket was in a completely different place. You guessed it, the filter was for a 327 Chevy. The guy at the store was pretty good about it. He gave me the right filter and five more quarts of oil, on the house. Still have the old Jeep, BTW....

Would have been nice to see bore/stroke differences between different manufacturers and characteristics ie chevy 327 was more performance oriented vs AMC having more torque etc

The author leaves out many obvious examples such as the 390s from AMC and Ford, the 331s from Chrysler and Cadillac, the 427s from Chevy and Ford, and the 360s from Ford and Mopar, just to name a few. He did refernce the 350s and 455s from Chevy, Olds, and Buick, but didn't feature them.

This article wasn't meant to be complete. The call to action at the end was for you to discuss the others.

In regards to the 350s and 455s, why give what's expected?

455 for Pontiac, Buick and Olds. 350 for Chevy, Pontiac, Buick and Olds.

I remember a neighbor's brand new 1977 Oldsmobile 88 which had a 350 engine in it. They loved the car up until the moment when they discovered it had a Chevy 350 in it. Traded it in on a factory-ordered 1978 Oldsmobile 88 with an Oldsmobile 350 Diesel V8. They stuck with Ford and Toyota ever since.

here is a double dose. Mopar's 5.7 Hemi is 345 cu. inches.. International made a truck V-8 345 cu. inches. Mopar's 6.2 Hemi is a 392 cu. inches. International also made a truck engine 392 cu. inches..

An obvious omission from the 383's was Mercury. "The 383 cu in (6.3 L) Marauder was the smallest member of the family. Produced from 1958 through 1960, it was only used in Mercury vehicles. It used a 109.2 mm × 83.8 mm (4.30 in × 3.30 in) bore and stroke. Output began at 312 or 330 hp (233 or 246 kW), both with a four-barrel carburetor. The 322 hp (240 kW) was the only output for 1959, and power dropped to 280 hp (209 kW) for the final year. "

I wouldn't call it obvious because it was a comparison between two engines within the same manufacturer--something that has confounded enthusiasts for awhile and will continue to do so.

Chrysler Corp. manufactured a 350 cubic inch B series engine in 1958 only. The information I have shows that this engine was NOT USED in high end Imperial and Chrysler cars. (Imperial was a different line from Chrysler until the last half of the 1960's) Dodge and DeSoto had a two barrel version while the Plymouth Fury could be bought with the (Golden Commando) a 350 B engine with two four barrel carbs.

Being 2.5 litre and V-8s are about the only thing those engines, and cars, had in common....

Buick engines were only available in the pre-AMC Kaiser-Jeep era.  Your Jeep musta been made before 1970.

When Olds came out with their diesel 350, everybody said it was a gas motor with diesel heads and injectors ... not true, the diesel was not a "gas motor", not the same block, far heavier.
