Im at my wits end here guys. In a previous round of mods I added a summit 1103 camshaft to my MAF TPI'd '82 T/A. I had it running well, but then i decided to replace the intake base and runners with higher flowing units. So, i just completed that round of mods and now i got problems. The first thing i noticed when starting the car is that when the engine cranks, it sounds... lopey? Not sure the best way to describe it other than that. it cranks around a little then slows down, then picks back up... (not even sure this is a problem, just different then before) when it does start, it runs real rough and dies if i dont keep the throttle pedal down. When i rev it, it stumbles and backfires a bit when i lift my foot (possibly rich?). If i unplug the MAF sensor it will stay running although a bit rough. Another thing i noticed when I reassembled everything is that the distributor is clocked in a different spot when the timing is set. I checked and the distributor is def. seated all the way down and the cap is on in the correct orientation (i thought i had the tab in the cap off of the notch in the dist. base.) I am thinking maybe the ignition module? although i have MSD 6a so im not sure it its even using the module in the dist... Also i am suspecting a bad MAF or possibly the MAF relay? I dont know, any thoughts? or at least tests i can do to check the MAF? I wouldnt think a sensor would be bad seeing all i did was change out the base and runners.

That sound that it is making, sounds like the same one my car was making when my timing was way off.

possibly pinched a gasket and created an air or vacuum leak.
