Actual Horsepower Of '60s/'70s Muscle Cars

[Ferrer]

Here are some figures from the book I mentioned:

Engine-----------------------Rated Hp--Est. Net Hp

'64 Olds 330------------------ 310------ 240
'66 Olds 400------------------ 360------ 320
'68 Buick 400----------------- 345------ 290
'68 Chevy 396 L-78----------- 375------ 360
'69 Pontiac GTO 400---------- 370------ 340
'67 Pontiac GTO 400 ram air--- 360------ 310
'68 Olds 400------------------ 370------ 320
'68 Chevy 427 L-72----------- 425------ 390
'69 Dodge 440-6 Pack--------- 390------ 370

'65 Mustang HP 289----------- 271------ 190
'65 Barracuda 273------------- 235------ 190
'67 Mustang 390--------------- 335------ 250
'68 AMC AMX 390-------------- 315------ 290
'67 Chevy Camaro 350--------- 295------ 230
'68 Plymouth 'Cuda 340-------- 275------ 290
'68 Ford Mustang 428---------- 335------ 320
(Note that the net rating for the 340 is actually higher than the rated gross hp!)

The Mopar Hemis gained hp as refinements were made. For instance the '68-'69 had a camshaft with more lift and duration compared to the '66-'67. The '70-'71 Hemis had hydraulic lifters while the '66-'69 still had solid lifters.

'66 Mopar 426-Hemi----------- 425------- 330
'67 Mopar 426-Hemi----------- 425------- 360
'68 Mopar 426-Hemi----------- 425------- 390
'69 Mopar 426-Hemi----------- 425------- 420

--------------------------------------------
Corvette engines:
Base 350-cu-in--------------- 300------- 200
350 L-46--------------------- 350------- 290
427 L-36--------------------- 390------- 280
427 L-71--------------------- 435------- 400

Fleet, that's really interesting. Thanks for posting it.

Albert, is that the first time you and Fleet quote each other without arguing?

No there have been other rare occasions where this has happened too...

I have to say some engines are quite disappointing, like the 289 Ford and the 350 Chevrolet.

Also the Chevy and Ford 302. The hp is okay, but 290 lbs-ft of torque is not that much... the garden-variety 318-2 bbl Mopar had 340 lbs-ft!

Well but 395Nm for a 4.9-litre engine isn't bad at all. The Mopar's torque is actually better in terms of specific output (460Nm from a 5.2-litre), but probably the smaller Chevy and Ford 302s would make the car less nose heavy.

Yeah, the 302s are not too heavy.

[-What-]

Anyone who thinks the 60s "musclecar" engines made a lot of power by today's standards is on drugs.

Oh no no no, I've already served them that cup of reality. Ya see, I speak the truth 'round this bitch but they don't wanna here non of that. So from now on, if you wanna fit in...see all those facts and common sense statements you brought to the table? Ball that shit up and burn it. Blank your mind of that because that's not what flies around here.

Because here, if you ain't rockin' at least 1000 posts you don't have the credentials to support your statements.

Because here, 400hp in 1960= 640hp in 2007. Yeah, all these acceleration and top speed records being SMASHED today and they believe 60's power was king. 2007 transmissions are thhhhheeeeeeeeee sh*t! Right?

Because here, "it is" = "its" and "it's" does not equal "it is".

Because here, "false" = "true as hell", and "truth" = "STFU".

Because here, THEY ARE NOT ME.


I solved this puzzle 7/13/2007.

I solved it 25 years ago...

But I think ACTUAL ARTICLES say a lot more than undocumented claims.

Don't you? Check back a few posts and see the ones I've posted... ;-)

Don't....do that.

Don't get smartass with me. You can twist, bend, and contort yourself in an attempt to out-manuever whatever I've got to say, but don't....do that.


I'm not afraid of steppin' out of the neutral zone. I got "it" in me. You don't...but then again...who are you?

No... you're just plain delusional 80% of the time. That's why you're a laughingstock around here.

this is indeed true for certain people....

First I would like to personally thank harddrivin1le for your contributions.

I am happy to see that the majority of people following this thread have now seen the light about how good (i.e not very by todays standards) '60s american V8s actually where and that they do indeed require overly high octane fuel and that their combustion chamber design was pretty bad.

However:

In fact, EFI can make LESS peak power, due to simple thermodynamic laws

This is simply not true. Properly setup EFI (we are talking multi point port injection here) will always beat a carb setup for whatever you want to do. You want power then program the system for power, you want milage then you can program the system for milage.

The funny thing is that when the article talked about advantages of carbs they attributed a measured temperature drop to the Joule-Thomson effect (which they misspelled with a "p" in thomson?) instead of vaporization of the fuel which the temperature drop is most likely to be caused by, and which an EFI system also creates and can take better advantage of.

And while we are at it I would like to say that direct injection tops both systems.

The boss 429 on dream car garage beat the 426 hemi and the 454

The boss 429 on dream car garage beat the 426 hemi and the 454

"Beat" them how?
The Boss 429 wasn't a very good street engine; it had huge ports (bigger than the Hemi's) and that hurt the low-end and mid-range. Then just about the time the big ports started to work on the top end, the restrictive carburetion and camming took over.

That was for 1969. For 1970, Ford engineers tried to upgrade performance of the Boss 429 by going to a more radical, 300 degree cam and solid lifters. But 1/4 mile times weren't helped a whole lot.

The fact is that both the Mopar 426-Hemi and the LS6 454 Chevy engines put out more hp than the Boss 429.
