I dont know if its been done or not, or even if you can search this stuff out. I think it would make a great reference thread. Somebody with a Chilton or some other repair manual that list HP and torque for multiple manufactures, could you post up numbers for popular engines.

Say, 1973 Ford 302, chev 305, IH 304, small mopar. 197x ford 351, chev 350, IH 345, Mopar 340. 197x ford 390, chev 396, IH 392, Mopar 383.

I'm really curious but dont have the resources.

Thanks

Dan, I tried to look this up for you but there are too many variables. For example there are at least three 1973 Chevy 4BB 350s ranging from 150-245 hp in the truck manual, not even looking in a car manual. Here's a few though, no guarantee on accuracy. All came from the same MOTORS Truck manual 34th edition.

All 1973 year

Ford 302 2bb 139hp/232tq

Ford 390 2bb 161hp/299tq

Chevy 350 2bb 160hp/265tq

Chevy 350 4bb 175hp/260tq

IH 304 2bb 147hp/240tq

IH 304 4bb 153hp/246tq

IH 345 2bb 157hp/266tq

IH 345 4bb 163hp/263tq

IH 392 2bb 191hp/299tq

IH 392 4bb 194hp/308tq

IH 304 4bb 153hp/246tq



A 4 barrel 304? That's a rare one.:laughing:

So much for the IH mills being torqe monsters:rolleyes:

I'd like to see how the mopars compared.

My 71-78 Chiltons truck manual lists
72-74 318 150hp/260tq 2b
71-75 360 170hp/285tq 2b
71 383 258hp/375tq 2b
71-74 400 180hp/315tq 4b
73-76 440 235hp/340tq 4b

88-95 tbi 350 210hp / 300 tq and will lug to 400rpm easy....
71 302 210hp
71 351C 250hp
72 327 chevy 190hp

Thats all the V8's I have lol!!!! my GSX made 350 hp on a Big 16G turbo 4 banger :flipoff2:

I think it needs DNYO charts to be of any real use.

A 4 barrel 304? That's a rare one.:laughing:
It had 2 listed for 1973.:confused:

The 304 2bbl numbers arent the same as the VIN plate numbers in the door jamb on either of my rigs, theyre a fair bit lower. The "book" say what they were like SAE net or some other such thing?

D.

my 5.0 stock

225hp/300ft-lb

I'd like to see how the mopars compared.

My '93 5.2 is 220 HP & 300 FtLbs but it weighs 578 with everything (All accy's, starter, exhaust manifolds, etc)

I'd have to say thats true.

A SBC may list out at 175/260 but that might be at 5000 RPM, were at the IH's 163/263 might be at 1500 RPM.


Depends on where the power is and if that power is usable to YOU in your application.

I'd have to say thats true.

That is mathematically imposable.

Hey Dan,

Keep in mind that the ratings changed from SAE Gross to SAE net in '72. The gross #s are always lower. Also, Ford and Chevy detuned their engines quite a bit in 72 (emissions). Chrysler seemed to have gotten by for another year before they detuned in 73.

Most of the manufacturers used less compression, leaner carburation, and altered cam and ignition timing. Ford actualy used 4degree retarded timing sets. I don't know if the others did the same. I know from experience that installing flat top pistons, a decent cam, and a STRAIGHT UP timing set will seriously wake up some of the 70s 'smog-dog boat anchor' Fords such as the 351M and 400M. :D

My '66 Bronco 289 was rated (gross) at 200hp/282ft-lbs. It had 9.2/1 compression where a '73 will have around 8/1. My 64 4V 'Thunderbird' 390FE (with 9.5/1 comp) that I put in a 65 F250 was rated (gross) at 300HP/425ft-lbs. That was a torquey bastard!

A 4 barrel 304? That's a rare one.:laughing:


I've never seen a FACTORY 2V 392 either, yet the book lists it. :shaking:

Of course 2V manifolds (offa 345s) actually exist that can be used on a 392. Now the FACTORY 4V 304 manifolds on the other hand...

They list a 4V 345 in 73. I don't believe that happened until the 78 Scout IIs (77 in California).

That may not be the most reliable source of info... :rolleyes:

Your not much better! :flipoff2: SII 4bbl 345 didn't happen untill 79, even in cali!

My first Scout was a 78, it was bought new from Edgewater IH in Oakland and it was factory 2BB with dual exhaust.

So with de-tuned motors they equal a regular tune IH?

I just hope this thread can be used as a reference when noobs start spouting about this engine or that.

Any caddy #?

Any caddy #?

Dan my motor stock is the following:

1969 Caddy V8-472 4 Barrel

375 Horsepower @ 4400 rpm

10.5 to 1 compression

525 ft/lbs of torque @ 3000 rpm


It really flexes stuff at low rpm too...

OK so I was only one year off, and I don't have the research staff that Motors has! I'm also just some knucklehead on a web forum, not some published 'authority' of automotive knowledge! That means that I was 5 years 'less wrong' than Motors! :flipoff2:

I've read in a few places that CA got the thermoquads a year before the other states. Maybe it was an OPTION (that your Scout's origional owner didn't 'opt' for) in Ca in 78?

New math? your two off. Carter Thermoquads and Cats came in 79 and never before! :flipoff2:

Absolutes in the world of Binders??? :laughing:


You've been lurking over at the BB too much! :flipoff2:


There's a reason why the parts catalogs and service manuals go by chassis #s instead of model years.

IHC didn't make neat model year changes like the Big Three...

That's why I've seen drum brake D30s, drum brake D44s, and disc brake D30s all in the front of 74 SIIs. I've seen 1968 Scout 800s with tapered shaft 19 spline D44 rears and single circuit MCs. In comparison, I've also seen '67 Scout 800s with flanged 30 spline D44 rears and DUAL circuit MCs. Strange...

You're just BB nit picking. My point was that Motors (a HUGE company that's SUPPOSED to check their facts) was WAY off. I was just incorrect in HOW FAR off they were. :shaking:

Just first hand exeperence. I bought my first Scout in 1980 and between myself and my friends Steve and Hugo, over 20 scouts and passed between our hands. :flipoff2:

Anyone have a dyno chart of a 345 or 392?

New math? your two off. Carter Thermoquads and Cats came in 79 and never before! :flipoff2:

My 72' T-all service manual shows the thermo quad.But I dont know if they existed then or what but the manual was purchased in 73'by my grand father.
I have never seen or heard of one before 79' either.

Hence that criteria when I was searching for a rig to buy:evil:

I knew Ben's rig had a phenominal motor choice that is in stock form...no after market this or bling that...

Just flat out big HP and Torque in a stock smooth running package.

One day I might inject the motor...BUT the QuadraJet runs the thing so damn well...

Qualify "beat" :flipoff2: Motors should be qualified by application, so what are we putting this in:flipoff2: There are a number engines out there that "beat" the Caddy, more HP, comparable torque, lighter weight, more reves, and blingly, but aren't cost effective. Hell the 2004.5-6 Cummins Turbo Diesel make the same HP and more torque at lower RPM's, is it "better"?

I don't know about "better" but the caddy would be a hellava lot LIGHTER :D

:shaking: What? :shaking:

I bought a 1978 Scout from the orignal owner in 1980. It came with the window sticker and the line setting ticket that showed were it was delivered too.

I don't know about "better" but the caddy would be a hellava lot LIGHTER :D


Yeah well, if weight it that much of an issue I can go on a diet!!

My numbers cant "beat" HOS, but I bet i get better MPG
I have a 6.5TD in stock form ..205HP @ 3400rpm, 440Tq @1800rpm
i have not dynoed it and cant find and numbers on my mods. I figued bout 250HP and 500Tq
i have reporgrammed the PCM and opened up the air & 4" exhaust and still get about 17-18mpg:flipoff2: :flipoff2:

I've still got the window sticker, lineset ticket, and dealers brochure from my '76. Buying a one owner two year old Scout would be COOL! I hope it didn't have much rust at that time! My '76 certainly did (three owner ex-Colorado rig).

The first Travelall I was exposed to was a CA spec '71 1010 2WD with a 727TF and a 392. It had all of the origional smog crapola including air injection (this was in '87 or so). The carb was a wierd Motorcraft 4V (similar to what was used in mid-70s AMC 401s). I've never seen this carb on another IHC (or in any IHC service manual/parts catalog).

We swapped on a QJet. It's been so long (I was in HS) that I can't remember if the manifold was a spreadbore, or if we used an adapter plate. When the Qjet ran right it SERIOUSLY woke up that 392. Because it was tempermental the owner eventualy installed a reman Motorcraft like the origional...

Can anyone beat the stock numbers of the caddy?
not stock, 71 lincoln 460 goes 365HP and 500 ft lbs at 2800.


however:flipoff2:

i did a real mild rebuild before i put it in.


heres the desktop dyno a guy did for me on another site


RPM HP / Torque
2000 208 / 546
2500 262 / 549
3000 314 / 550
3500 364 / 547
4000 408 / 535
4500 435 / 507
5000 439 / 461
5500 417 / 398

testy little bitches...:laughing:

I was just merely curious...As even I did not know what the Caddy motor put out when I bought it...:rolleyes: ...shows how observant of a buyer I am...ha ha ha.

Ben told me it was a mount twister and such...but wow...

I was just curious if there was any stock GASSER stuff that was bigger in our rigs.

I know of a guy in the SJ area running a 440 in his scout...rumor has it--the thing puts out 500hp.
