PK numbers

Do not confuse horsepower and torque.
You may be able to get circa 1985 360 horsepower out of your slanty, at some higher rpm. But you can never get 360 torque out of it unless you supercharge it.
And to tow 3000 pounds, with 3.21 gears, you are gonna need torque, cuz 65= about 2800rpm (10% slip) with 28"tall tires.
My guess is at 2800, it will take 150 footpounds..... or more. It's gonna take a lotta lotta throttle......
It would have to be a lot better once I get the new one built than the one in the truck now, and I'm thinking that if I had numerically higher gears that cruising I would be running even more revs.
And being an inline style engine like an old tractor with such a long stroke I'm thinking that torque should be plenty. It would have to pull better with less sense of "help me" (strain) than what I get out of the 3.9 v6 in my 99 dakota.
My 96 dakota (318 mag, 3.91s and OD) and my 01durango (360mag,3.55s, OD but nearly 275k miles) pull that camper like it isn't there.
I always hated how mopar castrated every 360 built with dished pistons. From almost day 1of originally creating the 360.
So now that you brought it up would you think that I should go low or hi stall?
