I wish they would use more low revving, pushrod truck engines in these new trucks. These new v8s are like rice rocket engines put together with how high they rev. Including the 5.4l v8.

 

Why do you think I'm happy with my V-6? It's a pushrod engine designed for a truck.

 

I love mine... or else I wouldn't have went back to it...

I was reading a good article on OHV and OHC engines, and not only did they say it was better for trucks to have low revving OHV engine, but so did a lot of the critics.

I love engines that have an OHV setup...

OHC should stay in cars and especially those little rice rockets/Hondas.

 

The torque peak for both the 4.2L V6 and the 5.4L V8 are at the same RPM, so there goes your low revving OHV engine theory.

Also, the Dodge Hemi which is OHV makes peak torque at 4400 RPM. The Chevy 5.3L also peaks at 4400 RPM, and the 6.0L peaks at 4200 RPM, both OHV engines. Their HP peaks are also at significantly higher RPMs.

Now the Ford 5.4L OHC engine produces peak torque at 3750 RPM, and peak HP at 5000 RPM. Hardly high revving.

 

Those are new OHV's... I'm talking like 460 big blocks... 1400 rpms at 390 ft/lbs of torque... Now that's smokin'...

 

Ore even better, the old 300 I6. THAT was a real truck engine. Slow as snails but would pull anything.

 

The engine torque curves and peak torque are not inherently part of the valve design. SOHC, DOHC, OHV, does not matter. One can design/tune the peak torque for whatever engine speed he wants. I don't see any problem with the Ford Triton V8's. They have more peak torque, broader torque curve, and get better fuel economy than those engines of yesteryear. If these new engines spin at 3500rpm, they are still quieter and get better fuel economy than the old school big blocks at 1500rpm.

One problem these new engines face is they are pulling 30-50% more weight in their trucks than 20+ years ago.

 

I wasn't aware of the 460 ever being available in a 1/2 ton.

Anyway, you wanna compare that to the 6.8L OHC V10? It's said to make 80% of it's peak torque, which is 457 ft/lbs, by 1000 RPM. So at 1000 RPMs the OHC V10 is making ~366 ft/lbs. It'd be a safe bet that it at least matches the 460 through the entire powerband, and beats it through most of it. But that can't be since it's an OHC rice rocket motor.

 

I believe the 460 was a 1/2 ton option from 1973 to 1979.
