You'd have had cognitive dissonance driving that V12. Big bore, short stroke, low revs, high torque... bring LOTS of gas.

Hey, I'm just a dumb ex-farmer here, don't use such big words
. Actually, there's be none. It'd be just 2 cyl. better than the V-10! (but they weighed like 1,400 lbs...wow!There's that link, I couldn't find it. Oh yeah, lotsa gas, can't remember what bro.-in-law said it got....BUT...
Inaginge what a powerhouse it would be now with tuned intake/exhaust, EFI, and high energy ignition.
Bad part about those engines then was the fact they had the spark plugs inboard of the valve covers, much like our modular Ford engines, but with conventional plug wires and boots. Heavy snow would blao in, melt and drown out your plugs if boots were not new...maybe even then.

Imagine what a powerhouse it would be now with tuned intake/exhaust, EFI, and high energy ignition.
Bad part about those engines then was the fact they had the spark plugs inboard of the valve covers, vertical, much like our modular Ford engines, but with conventional plug wires and boots. Heavy snow would blow in, melt and drown out your plugs if boots were not new...might still, even with new wires.

Also, in the late 70s they started calculating hp and torque at the rear wheels.
Now it's all at the crank.
So something that makes 200 hp at the rear wheels could easily be 260 at the crank.
The 5.4 in the new F150s makes 300 at the crank, but about 240 at the rear wheels...

Just FYI......Manufacturer HP/Torque ratings have ALWAYS been at the crank.
Yes, it it changed from gross to net in the EARLY 70's.
It also changed to SAE NET a few years back which was supposed to standardize the rating.
And that 300HP 5.4 is closer to 220 at the wheels.....either over-rated or some major drivetrain loss.
