thanks for all the replys this weekend is "work on the charger w/e" some facts, the carb is the edelbrock 1401 or 14xx cant remember, its the same on my challenger and it works great, i dont think its the carb. vacum advance is hooked up, wires are on corrrectly, fuel doesnt seem to be an issue,i have a electric pump, it does pop thru the exhaust though, maybe bad exhaust vavles? i'm leaning towards a bad cam. i'll report my findings this week.

TIME to find-out what your fuel pressure is.
I agree, you need to find out your fuel pressure.

You know the word CRAB was an error in spelling THEN it stuck ... 'specially ferr 'da Bumz MY experience with this situation .. I have had a combo go lean and fat. Lean was when I was doing some major tweaking on a TQ ... I changed the secondary jets and FORGOT to tighten one down. It fell off(and that cut-off 50% of the fuel in the secondaries) ... then the car was popping and banging SURGING big-time. Later that month I took it to the track..... muffs, OEM dual-snorkel air-cleaner and all..... it would lazy nose-over when you got into the higher revs .... MPH was not what it should be. I double-stacked the AC element ... problem solved THAT situation was going way FAT.

I have the Eddy 500cfm and the eddy 750. If you put your foot down, maybe you need some more fuel. Is your accelerator pump linkage on the middle hole? Try readjusting it to the bottom hole, it will allow more fuel to come in. Your jets/rods would be another question. They are usually pretty good from the factory but you have some fine tuning in your future to perform. Are there any vacuum leaks? Is the back port on the carb sealed? I have vacuum lines coming off mine and maybe you have a fray or crack in yours. I have but one car and I saved up some cashola to buy an Air/Fuel readout so I can fine tune the carbs. If you have another carb as you say...doesn't hurt to spend 15 minutes and take it off the other car, all the fuel lines will hook up the same way too. How many miles you have on that cam? Hydraulic? Solid? If you think its the cam I dunno how to go about checking it. It'd be the blind leading the blind...maybe pull a lifter and check the bottom for damage

Hate to add fuel to THIS fire.. but if the engine IS NOT rebuilt- He may have excessive slack in the timing chain, or he may have slipped a tooth. Wouldn't show up at light throttle, but would alter the timing enough to cause an issue under load. Stupid Plastic-toothed 'Silent' drives were known for this kind of issue. Just my CC
