Resto mod may not be correct terminology. New Hemi orange correct paint and interior. Correct Dana 60 and 4 speed. Just Centerline wheels. Street slicks. Sub frame connectors. 3.5" exhaust. Hooker headers. Gauges. Not a big deal It would be an easy conversion to bring back to original. Wheels, tires, exhaust, 390 hp 440 and other minor things. I just couldnt be happy with those lame wheels and skinny ass tires. 390hp wont do it either.

WOW heee hawww get the ash end down son! More about the set-up please. cam.. headers? Stall sand so on. With all those cubes I'd guess you'd want more jet and more squirter than stock? How are the carbs set up now? Do you have a regulator? I'm at 6.25 all the way down the track. I'd think anything over 7 would be a tad high. How are you floats? too high and it will push gas big time. What PV? what is your vacuum at idle? Need more info to help.

I did a resto mod on a 69 Hemi orange A12 Six Pack Super Bee 4 speed. 440 to a 543ci stroker. Edelbrock ported heads. Full roller. New six pack set up. Dyno last month @715 ft lb of torque. To watch air fuel ratio I added an air fuel sensor in the exhaust. It runs very rich. 8 to 10:1 ratio. Very rich. I swapped the new carbs with the Six Pack carbs on my other Super Bee just to test. Those are modified and jetted up. Same results. Rich. Most people told me if anything the new stock Holley carbs on a motor like this would have the 543" running lean. Just the opposite. I think the problem may be that ive used a Carter high volume fuel pump. Its the one they sell @ 440 source. Is the pressure too high causing fuel to push past the needle and seat? The other Bee with the same carbs does not run rich like that. Ive ordered a Holley regulator winch will come next week. Could it be something else? Thanks in advance.
get the fuel pressure down and make sure you use a the high volume holley regulator. also, make sure the power valve is correct for the engine vacuum.

and you thought the factory wheel and tire combo looked wacky? 
that's a nice car with a terrible selection of wheels, tires and sizes. also, consider that your paint job on the quarters will be thrashed in short order with the tires jetting out so far beyond the wheelwells. 69 coronets have plenty of room in the wheelwells to fit a good sized tire without making the car look clownish.
again, nice car!
haters, all of you  i like the look so don't listen to them OP

You build your car any way you want Shawn. Would you listen to your neighbors when you pick a color for your house too?
BTW: There seems to be a ton of 6Bbl. information surfacing recently. Glad to see people sharing on setting these systems up. I just re-vamped mine with different jetting & diaphragm springs and what a difference!

OK, just pump the brakes for a second. This pic was taken before the car even was on it's first test drive. Removed the read end during restoration. Pic was taken with incorrect rear shackles were on. Now that I've driven it working out these bugs it does not sit up high like that. It looks bad ass with the street slicks. Rake is perfect for me. I ordered the Holley regulator from Summit. I see someone above mentioned a high volume Holley regulator. Is this the same thing? Am I on the right track with thinking Carter pump is the problem?
No That's NOT your problem, save your money.
I'm sure the tuneup is in left field. Start with your distributer, that's where your problem lies, imo. Tells us about it.

I don't understand this..
"New six pack set up. Dyno last month @715 ft lb of torque."
Was the tune rich then? Doesn't your dyno guy tune the engine?
You still haven't answered how the engine is set-up and how you have the carbs now. I have found the 6-pack is just like any other carb'd car. You have to start from square one and go step by step. For your application, given the cubes I'd start out w/ 70 jets, 35 squirters, 6.5PV and maybe the plain springs. I'd turn the mixture screws in all the way in then back them out 1.25 turns. I turn the idle screw up to and start the car. I let it run at about 2200-2400rpm and set the total timing at 36* (don't forget to unhook the vac advance if you are running one) Then I'd turn the idle down to 900-1000 and adjust for best vacuum and check initial, it should be around 16-18*. Then you can go for a test drive. Check for flat spots, bogs and whatever else. Pay closer attention to how the car responds and no so much the a/f meter. Do that and get back with us.
the fuel pump he installed is the carter high volume. it has a fuel pressure rating at 8-9.5 psi. put in the regulator, get the pressure down to 4ish and then do the above.

If it idles at 6 to 7 inches of vacume and the power valve is a 6.5 change it to a 4.5 and tune from there
