Re: 302 to 351w swap
Actually, the swap should be pretty straight up. That year is a full sized pick up, the 302 and the 351 are both Windsor blocks, and there's oodles of room under the hood. A new engine comes with a better warranty, but a higher price. If you go used, you're going to want to tear it down and have it machined and refreshed, in the long run, that might cost you more and require a lot of work. As a word of advice, keep HP and torque in the 300 region unless you plan on going into suspension and performance tires. I have a 73 Ranger and I figured I'm putting out a little over 300 and the rear gets real squirrely when I get on it. I'm also running some pretty knobby tires, so that doesn't help, either.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
