HEEELLLLPPPP!!!! 82' Fleetwood Brougham on the fritz!
 

Alright guys, here goes nothing:

About 15 years ago my dad bought an 82 Fleetwood Brougham from my cousin. The car had a carburetor-ed Olds 307, but everything worked. I got the car around 2005 and I blew the motor. I replaced the 307 with another 307 and I've had problems ever since. The A/C stopped working, starting having all kinds of electrical problems and I just come to the conlcusion that I need to have the car rewired. The only problem is NOBODY seems to be able to do ANYTHING for me. I've had several people look at the car and noone could give me a definitive answer. I need my baby to run again. Is there anyone that can assist with this issue? I do understand that the original motor was a fuel injected HT 4100 so I'm wondering what engine would be a suitable replacement? I would rather go back to fuel injected but really the issue is the wires and the electrical issues. HELP!!!
