don't "see" anything; but, if it starts and runs, and is complete, yeah; it's worth saving. as far as what you can put it in, Ford pickups, open cars, '50's Fords and Merc's... it's big and heavy and can be hard to find hop-up stuff for, but dead reliable and strong as oxen. they can blow head gaskets and overheat, but what can't? buy it, clean it up, run it in the HAMB cl***ifieds.
Sure it's worth saving. Big and heavy but they're nicknamed Bulldozer for a reason. Make certain the crank driven PS pump is on there... these are expensive to replace. Same goes for the exhaust manifolds but to a lesser extent.
The 430 is a big MEL block. Some of them found their way into Squarebirds from the factory. It could be a nice motor for the right build.
No aftermarket goodies for them and there never has been as far as I know of. We had a 430 in a 58 Merc Colony Park wagon years ago that ran like a bandit and was dead nuts reliable. I wouldn't buy one to "build" for a car but would put one in a cruiser or a truck that I wanted to make serious road miles with and expect little or no trouble out of it.
Don't listen to the Chevy guy. There are aftermarket speed parts for them, you just have to do some (maybe alot of) digging. Edelbrock made a couple of different intakes, you can still get performance cams, and there are header flanges available. Check out the MEL Forum for more info. http://ford-mel-engine.com/ And for 150 clams, please save it.
Great torque monster engine...However, just like FE Fords they like to eat exhaust manifold gaskets, so you might as well fight the studs now 'cuz you will certainly fight them sooner or later and better on the shop floor or stand than already in the car/truck For a buck and half save it
