1972 Ford Pinto with 460 Big Block Dyno Run 

Ford definition, backwoods, to say it nicely driver returned on foot,just saying,!!!

???? I have a 68 Chevelle with a 454HO. It has 8 3/4 to 1 compression. Also, on the chassis dyno with a 830 double pumper and long tube headers and a turbo 400 mine made 348 hp and 372 ft. lbs. of torque. Your numbers are very low.

The 454HO is a crate engine with 438 hp and over 500 ft. lbs. of torque. It also has forged internals, four bolt main bearings and 8 3/4 to 1 compression. The earlier years only claimed that it made 425 hp. Or....are you referring to the LS7 454?

Technically Canada.....so I guess North 'Merica

Amen! Finally someone that gets it

Awesome. Yes. Guys who know and have built cars know , we know it takes trial and error and many redo and remake stuff. Dial it in takes time. No build will be perfect first go . This 460 appears to be tired or just a stock 460 with no real power made yet. The power is easy to make in a 460 , it's all the bugs in steering and suspension and driveability that need to be solved and dialed in before add 1000hp or more. This is great little pinto and it takes time. Power is easy part really . All the dialing in and fine tune takes time

I agree. Good numbers for a smog era 460.

Exactly!

Nicely done!

There's no replacement for displacement!

@@dynomiteperformance that's right why I shoved a 5.4 in place of my 4.6 in my 98 stang

@@bigmikelongwood3276 how about a v10 instead!?

I definitely think it's a popular drag car platform!

No, not a misprint.

The D0VE heads (pre smog) are pretty good for a stock application, but no comparison to the aftermarket. There's just something about big block NA power!

​@@dynomiteperformance Yep....the stock exhaust ports are just awful, along with monster sized oval intake ports A set of OEM Explorer 5.0 GT40 heads flow the same on the exhaust as stock 460 heads!

Sorry to break your heart but we run the same settings all the time. SAE correction factor which is the standard that most dyno operators use. Also keep in mind that numbers given are hp/tq to the rear wheels not at the crank. So that 661hp would be closer to 800hp at the crank.

The 460 is known more for torque than horsepower. We really didn't have time to talk to the owner about his setup because the event was so busy. I'm guessing it's a post 1972 motor which has a stock hp rating of 240hp.

@Zahara Greene Pretty much all the old big blocks from any manufacturer made 400 horsepower until the late 60s I believe. Or at least they could with a big carb and tune up. I want to say the 460s were the least powerful at 340hp, 440 Chrysler got close to 500hp. The small block fords could make 400 with a camshaft and carburetor. Everything tanked when gas got expensive because high octane gas has a low energy density and wont get you very far. People didn't want cars that got 8 miles per gallon so manufacturers stopped making them which is why compressions ratios dropped.

Stock hp numbers for the 460 after 1972 are only around 240hp and 350ft/lbs. With the wide open exhaust like on this set up you'll lose a ton of torque. Also keep in mind the numbers above are crank hp and the numbers we recorded are wheel hp. Typical losses from crank to wheel are 15 to 20 percent

@@dynomiteperformance you have the wrong algorithm. So many times I've seen these portable dynos record big HP on a fuel injected vehicle and way low numbers on a carbureted engine. The HP rating of the 1972 460 engine by Ford was to appease the government. Not actual power output. Even a smog era 460 typically will produce 295-310 rwhp on a corrected dynamometer.

@@brandonhumphries3377 time, rpm and speed are collected the same way regardless of efi or carb set up. Hp and torque are merely calculations derived from the parameters mentioned above. Since driveline losses will vary depending on the vehicle, chassis dyno results have to be taken with a grain of salt. If you want true numbers then you must pull the motor and use an engine dyno.

@@dynomiteperformance that's not necessarily true. But no sense in a pissing contest.

@@brandonhumphries3377 what type of dyno do you have?

Could be. This was a one run and done so not sure what ever came of it

I believe it was a stock frame

@@dynomiteperformance damn I Own a Pinto wagon got it sitting on a 84 Bronco II frame I’ve been building for drag. Have a 460 I’ve been wanting to use but was told it would bend the frame

Yes. A chassis dyno measures at the wheels. Probably about a 20% loss from crank

No these were the numbers. A post 1974 460 is not a powerhouse. This is what they make to the wheels

@@dynomiteperformance ok , forgot its post 1974 , I was thinking earlier.

Everyone seems to be quick to judge. Maybe this was a baseline run for him before throwing some go fast parts at it.....just saying.

I'm not sure. This was a couple of years ago so who knows where it is now

I believe it was a fairly stock motor other than an aluminum intake and headers. Most likely this has the D3VE heads

A similar year 454 would make similar power. Smog Era motors.

Maybe he was trying to keep it period correct.
