New to the Mopar scene.. got 68' cuda need help.. new motor...

Hey guys... im new here and looking for some help and to learn as much as I can.

I just got a 1968 Cuda notchback. It has a 440/727 combo, aluminum edelbrock heads fully port matched with intake/exhaust, headers to 3" exhaust, 1050 Race Demon carb, Weisco piston's, 10.2:1 compression (just lowered story to follow)...

i bought the car about a month ago and when it was delivered to me the motor started up but instantly started Knocking... i opened up the heads and found the carb airstud in the cylinder... long story short the guy left out of town and left his son in charge of meeting with the transporter... kid swapped out parts for his buddy's car and dropped the stud in there but replaced it so everything looked normal... guy was GREAT and paid in full for repairs... in doing so i dropped the compression down to 10.2:1 to run on pump gas..

all parts back to normal and got the motor back, all parts the same as when the guy owned it and it did run great.. my bro in law up north checked it out in person and gave the OK and said it ran like a bat out of hell...

leads me to today... got the motor in yesterday and took it for its first drive down the street... and its HORRIBLE...

at idle its cool and sounds healty and fresh but once you put it under load its like a 4cylinder beater.. spark is kinda weak and i checked voltage at the Coil and its only 6.0volts... whats wierding me out is that it has an electronic ignition but is still running through the ballast resistor.....

another thing is i have the timing set at 14* and it cranks smooth but i notice the vaccum line from the carb is capped off... so i dont know what my total timing is (gun isnt adjustable and no timing tape on the balancer)

so im coming to the conclusion im not burning the fuel...

ive been out of the muscle car scene for about 5 years and im getting back in the swing of things so im curious to hear any suggestions as to why its lagging like a dog?

Thanks
