lemon law on a rebuilt motor?

What is the name of your state?AZ
I recently bought an older truck, a 76 GMC K1500 Sierra Grande, from a private owner. I knew it needed work when I bought it. I took it to have another motor dropped into it, because the motor in it wasn't good, and was heavily modified. After getting quoted $1500 for the whole job, I bit my lip when it ended up being nearly $5000. The rebuilt motor came with a 3 year, 36,000 mile warrenty. After having it for one week, it cracked a head. I took it back, and they put new heads in, but they "claimed" to replace the distributor that THEY replaced. All this cost me an ADDITIONAL $522. They CLAIM that the warrenty only applied up to $350 dollars, and their labor rate jumped from 36 an hour to 68 an hour, and I had to pay for a new spark plug, new coolant, etc etc**************..Another 2 weeks went by, and the motor wouldn't start. I got fed up, and did the work myself. I had to replace the distributor that was supposedly replaced, but when I looked under the distributor cap, there was an old rusty coil. I replaced the whole thing, coil, distributor and everything associated with it. I want to take them to court for the money I had to shell out, plus the other repair (I failed to mention NONE of the work was timely nor convienant). Is this covered under the lemon law, and do I have some validity with this issue? Thanks in advance for any advice you can give me on how to handle this issue.

*** No.

As to how to handle it... I would file complaints with every local and state consumer or licensing folks I could find. Including:

Simply, you are being screwed without being kissed.
