So far yes, I mean bothy wife and I are currently unemployed- due to shelter in place orders, and she has not received 1 friggin penny so we are living on my unemployment wages.... UGH, but at least I have something to do .

Thank you all.

Next step is to remove stubble from carb, I will pull my wideband from my race Civic (1.6 liter 453 whp, 31 PSI) and put in the coronet.

See where my AFRS are actually at.

That's a must have in my book for tuning carbs. Takes some guess work out of it. I have had one in my car for about 10yrs now. Great tool to have.

the only thing i can add about a temperature gun versus a gauge, is a gun is measuring the surface temperature, while a gauge is measuring the actual coolant [internal] temperature.
with that said, i would expect the gun to be about 15-20 degrees [10 maybe ?] cooler than the gauge.
just my opinion. your mileage will vary.

i agree, but 50-70* difference, i don't think so!


on a different note, i am swapping out the stamped 727 deep pan for a cast version, which will hopefully stop the leak at the trans. the question is, do i need to add a deeper filter pickup? the old pan has a 1" deeper pickup in it, but the new trans cast pan is about 1" deep than that. do i need to be picking up from the bottom???

If you dont pick up from the bottom thats just wasted fluid.. they make deep pans to help cool

bought a cheap $20 mechanical gauge, it reads on point with the infrared gun... awesome, nothing like a chinese 20$ POS being more accurate than $100 USA made POS flame Car does not over heat, it probably never did. 3 gauges with matched sending units all busted. JUNK!

New question-

this car has a Hurst pro-matic 2 shifter, and it has melted several shifter cables, i have ran shorter longer etc... wrapped in heat shielding... but they all seem to die.
I have a Lokar shifter, but on this B body it will dang near be under the dash.

what other options are out there?

Melting the shifter cable??? Maybe you need a ground strap from your engine to the battery? I am anal about grounds and besides every ground in my car going back to the battery, my engine, heads, and trans all have ground straps that go back to the battery .

i like the look of the winters, it seems like a simple easy shift pattern as well. I think my pops would like that!
Thank you for the suggestions.

I had it wrapped and zip tied as far away from the hears as it could be, took a while, several starts and such before it melted, but it did.

I just added a new ground actually from the motor to the chassis. But it is melting due to heat. the car has the schumacher heads and there is just no room to keep the cable away from the heat. I think i may do the rear exit shifter.

thank you all for who has helped and chimed in.

Here is the car, the bumper is now back on and is satin black to match the hood.

Timing is at 18* and it still pops, backfires through the carb when under load at low rpm... i changed the accelerator pump cam position and it made no difference.

Try enrichening the idle mixture screws, idle air bleeds smaller, and the transition mixtures, popping is usually to lean twocents

Nice looking car,

Thought you mentioned you had another carb you could try.
I would do that and see if any improvement.

i pulled the carb apart, no issues with power valve or jetting. it is a holley 870 avenger. verified jetting for this carb etc..

however the power valve did have 2 gaskets on it. I pulled the PV and it had one on it and one of the metering plate. thinking it split i inspected it and compared it to the 1 replacement i had. I had 2 gaskets from the factory. I hope it is supposed to only have one. Thats how it went back.

thinking now maybe it is time for a cam swap. after talking with my friends, many of which are professional gear heads we have tried and ruled out just about everything that could cause this backfire.

The one thing left is maybe the comp cam custom grind they did for this engine is messed up??? shruggy

I also want to get a little more vacuum back into the engine so I am thinking if something sub .500 lift. mopar 484 cam?

id love to see this motor make some decent power, right now it does not. it is slow, weak and underwhelming. id think a 10 to 1 383 with stealth heads, harland sharp rockers, 1 3/4 headers, m1 intake and 870 vac carb would be snappy and fun. the car has 3.91 gears and a 26" tall rear tire.
I know 400 is very attainable from a 383 of this build- do you guys think a mopar cam is the way to go?

NOOOOO tsk
Is this cam degreed? If not do that first.
If it is degree what are the specs on the duration at .050 and LSA and intake lobe center?
I'm still thinking you have a lean pop at light part throttle application, driving twocents Or maybe a vacuum leak work
