Here's a devils advocate question for you. If you stumble across a motor that you have no idea as to what it origionally came out of (for instance a '73 4WD with a 460, and it has had a backyard rebuild done to it (a can of spray paint) How do you tell where to set the timing then?? It could be anywhere from 6* to 16*??!?!?
Im alittle confussed about this 73-79 specific thing..... If i dont know what the engine came out of but it is in a 73-79, wouldnt that kind of make it a question for the 73-79 forum... ? Ive seen this a few times. Yes if the question was just about the 460 then it isnt a specific questiond but if it is about a 460 thats in the right type of vehicle would that make it a specific question for both forums? Im just wondering about this because it has happened to me also.
Just a thought..
One way that I've heard of checking to see if a 460 is original is to see if it is 4-wheel drive. To my knowledge, the 4-wheel drive trucks did not come factory with a 460. I was recently looking at a 79 F150 4-by-4 with a 460 in it, just from that I knew it wasn't original, and I was right. Regardless, it sounds like a good buy, but check it over real close to see who installed the engine, and look for reciepts so you know what went into it - to see if its a new engine or a jury-rigged rebuild.
