My 351W in my '70 stang stopped working altogether. Here's a summary of what happened.
It always had difficulty starting. Around 3-4 cranks to get it to turn over. It progressively got worse, and then it finally stopped working. One day, I kept trying to get it to start, cranking it a bunch of times, and the solenoid started smoking... So I immediately ran to my classic mustang supplier and got a new start solenoid and stuck it in. Sadly, however, my Windsor seems to have died.
Things to keep in mind: someone working on my car stole my brand new battery and replaced it with an incredibly old one. My resort is to hook the old battery up to a fully charged battery through jumpers, but it still doesn't start. Old batteries don't fry solenoids do they..
Can I get some ideas as to why my 351 isn't starting? I need as many ideas as I can get.
I'm wondering if you might have jumped time. If it progressivly got worse maybe the timing chain was stretching and got sloppy enough to jump a tooth?
Do you have spark when you crank it over? Do you have fuel when you pump the carb? Basically you need three things to make an engine run, air/fuel mixture, spark and timing. If you have spark and fuel I'd check the timing.
is it turning over at all? if not it could be the starter
it used to AT LEAST crank a bit, but now it doesn't even make a sound. i hear a lot about having a "strong" battery is needed to start an engine. is hooking my mustang's old battery up to a new battery through jumpers the same thing?
if it wont do anything when the old battery is trying to crank with a jump try the good battery as the primary. check your battery cables both poitive and negative cable for corrosion. if in doubt buy new cables. smoke means drawing too many amps from either a bad starter or bad connection meaning bad/dirty cables ect. wes
My bad, I misunderstood the question. I thought when you said you were cranking it the engine was turning over but not firing.
As others have said, replace the battery with a known good one and check cable connections. If it still won't turn over I would suspect the starter but since you said your battery was replaced with an old one that would be the first thing to check.
Maybe you need to refill the solenoid with fresh smoke, since some leaked out before?
(Sorry, I just couldn't help myself...)
, seriously put in a new battery, then try it, if nothing at all, starter must be bad, especially if it is not clicking after you've changed the battery..check connections of battery-solenoid-starter...start with that and then keep us posted...good luck

I had a similar problem once. The factory cables are a smaller guage than newer cars. The factory batteries had less cranking amps than newer batteries. Basically, the cranking melted the positive cable and wouldn't allow enough juice through to start the car. I would guess that you smoked the solenoid and maybe even melted the positive cable in the process. If the cable is melted, you will feel it. If the cable is smooth, then it didn't melt, but if you feel a depression anywhere, change the cable.
Like the others have said, try a fresh battery instead of trying to jump it. If it doesn't crank over, then check the starter. If that doesn't work, then check the timing. This is the order of least amount of work to most amount of work.
