That having been said, do you think I could pull a DMC-12 with my 3.0L
Ranger? (I'd be using one of those "dollies" which allow it to go on
two wheels.) I forget the tongue weight - the manual's in the glovebox
right now and I'm at work. How much does a DeLorean weigh? 2700+ lbs
IIRC ... any more precise figures out there?

Andrei, Andrei, Andrei -- don't fall into the HP trap.
Horsepower is calculated from 2 numbers: Torque and RPM's. An

does so at 1,500 RPM. Do you suppose your Porsche -- with the
rating -- could pull 80,000 lbs as that tractor does? The
answer is of
course "no" because it would never be able to rev anywhere

Domestic big blocks have tremendous torque -- 3 or 4 times as
a little sports car engine. That's why you see people towing
trailers with a Cadillac, but never a Honda.
FYI: HP = Torque x RPM / 5252.
The 450 HP rating of your 454 is probably a gross number,
out of the vehicle with no accessories on the front. That's
American manufacturers did it in the 1960s. Actual net HP in
averaged a hundred ponies or so lower. Domestic manufacturers
to net HP ratings at the same time they dropped compression
lower compression does lower HP, but not as badly as the 1972
make it appear.
If you're having problems with the 454 in your boat, consider
460. I know it's a popular marine application.
