Q: I have a Dodge D150 pickup with a 360, and this old kid’s really hoping to reach 425-450 horsepower. As luck would have it, I happen to have a 440 from my brother’s old motorhome—it only has 35,000 miles on it and I’d like to drop it into my pickup.

Using this engine, would I be able to reach my horsepower goal, and if so, would you help me pick out the necessary performance parts? Or do you think I’d be better off working on the 360 that’s already in my truck? Thanks for the help!

A: As the old saying goes, there’s no replacement for displacement.

There are plenty of go-fast parts for your truck’s old 360, but the opportunity to drop a low-mileage 440 in your hauler is just too good to pass up.

To reach your horsepower goal, we recommend starting with Edelbrock’s Performer RPM high-rise intake manifold, cam and lifter kit, and cylinder heads, plus a Performer 800 cfm carb.

These parts are designed to complement each other perfectly and produce plenty of power.

While you’re at it, upgrade to some Harland Sharp adjustable rocker arms to really dial-in that 440.

If you’re using an automatic transmission, you’ll also need a torque converter in the 2,200-2,500 rpm range, like a B&M Holeshot, and some 3.73 gears to get all of that grunt to the street.

Finish it off with a free-flowing exhaust and your pickup will be a very streetable powerhouse with more than 450 hp that still runs on pump gas.

Not bad for an old motorhome engine!
