To start with I'm a lot more familiar with small block Chevy engines since that's what I've built and I currently have a 66 Chevy II. Anyway, I have bought a 64 Falcon 2 door hardtop and the guy has a 302 and AOD transmission that he pulled out of an 89 Mercury Grand Marquis that had a little over 80,000 miles. I'm assuming this would be a roller cam engine. I intend to remove the fuel injection and switch back to a carburetor. I know, why would I want to do that? It's because I just don't like to see a modern looking engine when I raise the hood of an old classic. That's just my personal taste, no offense to anyone. Anyway, I know I have to switch timing chain covers to run a mechanical fuel pump and switch intake manifolds. I plan on changing cams to a little better one but I'm not sure which would be the best one for it. 302 roller cam and lifter kits are terribly expensive. Are there some good ones from Ford Racing? One thing I'm unsure about is the heads. Are the heads on these any good or do I need to switch to different ones? If so what are some good cast iron heads to go with? What are some good factory heads? I'm not interested in aluminum heads. I need to know what type of torque converter to run with the AOD and probably a 3.55 rear gear. I won't be racing, it will be a cruiser but I want a pretty good motor in it. Any information I can get would be great.
