[DeTomaso] 1972 pantera

[Garth Rodericks]

It's a worthless piece o' crap Robert!  I'll give you $5,000 for it right now!   :D

Seriously, don't lose heart!  We've all been there. Where are you located?  Maybe some of 
us are near by and can come over and lend a hand.

Did you pull multiple plug wires while changing those plugs?  Double check that they're all 
back on the right plugs - Ford cylinder numbering is different from Chevy (if you're a former 
Chevy-man). 

351C firing order: 1, 3, 7, 2, 6, 5, 4, 8

Also, does the car have an electronic ignition of the original dual point distributor?  I had 
the exact same chug, chug symptoms when my car had the original dual point distributor 
because I checked the point gaps and managed to drag the tiniest bit of grease from the 
distributor cam through one of the points - ran like crap when I finished.  As a matter of 
fact, I did this several times while trying to reach over the engine to check the darn things, 
and didn't realize I had done it either time until I had buttoned everything up and tried to 
start it. Just a thought.

Also, be sure you're using a FelPro gasket for your carburetor. I've found that some of the 
Holley gaskets (and various parts store gaskets) do not adequately seal the carb base, 
resulting in a vacuum leak and poor running conditions, but not quite chugging like you 
describe.

Good luck!

Hello again from the newcomer .
 
I am totally frustrated with the car now. Heres the latest. Last night I  
opened the carb to clean the jets,floats ,fuel lines etc,Pulled a spark plug and  
saw that it was as black as the ace of spades. I changed all plugs ,remounted  
the carb after thorough cleaning.
Went to start the car and thought she would  
purr.Instead.....chug,chug...chug...remove my foot from the gas peddle and she  shut down.tried adjusting 
idle,mixture screws on the magnificent 4779-7(750cfm)  holley.Went to start her up 
again....same  thing...chug...chug....chug.....stall...i pushed her back into 
the garage and  tonight I am going to change mounting gasket per holley the 
gasket should be an  open square instead of four circles.I will also as per 
holley adjust  the idle screws to all the way in and then back out only 1/2 
turn.My  fingers are crossed that this will cure all of these headaches. 
I am still open for all suggestions. I will try anything at this point  .
