And torque really applies depending on where it is in the power curve and rpm range.

The 360 V8 has stock HP of 255 at 4,400 rpm. The torque is 360 ft-lb at 2,400 rpm

The 4.7HO V8 has stock HP of 310 at 5,000 rpm. The torque is 329 ft-lb at 3,950 rpm.

THAT's really where and why you feel the power of the 360 versus the 4.7HO. The 360 has more torque for sure, but LOTS more torque 1,550 rpm sooner than it does for less torque in the 4.7HO. Given that much difference in torque SO much lower in the rev range, I'd bet the 4.7HO has less than half the 360 torque at 2,400 rpm.

Which now has me thinking, tuned 360 with EFI for my 56 versus the 4.7HO? The 360 makes SO much more torque at lower revs that the 4.7HO cant even match at higher revs. A crate 360 from Powertrain is about $2500, while a 4.7HO from Powertrain is $4300. I had thought of using all the engine accessories off my 2001 4.7 for the 4.7HO to save money. But for $1800 I can buy a LOT of 360 upgrades and get even more HP and Torque. I wonder though what a strong tuned 360 with EFI loafing along the highway at 2,000 rpm would get for fuel mileage? Could a 360 with a bit of a tune for power, headers, EFI, Magnaflo exhaust and connected to a 66RFE trans with the 0.62 2nd overdrive get into the mid-20's at 75mph on east flat terrain? Torque really does the work and I like an engine that doesn't have to rev over 5,000 to make all the power I'd ever need.
