Hi everyone,
As always, I appreciate everyone's help. This community has been great as I work through the many issues with my Cuda.
What I have here is a mystery 440 6 pack. The guy I bought it from had no clue about the engine, so I have no idea is it has a big cam or anything done internally. What I do know is that it has a MSD6al and a holley electric fuel pump pushing 7psi, Hooker Comp headers, vacuum advance on the distributor is plugged off (as well as the carb port for it)
When I got the car it would fire up but not idle at less than 1200 rpm and even then, it was so rough the whole car would shake
I've replaced plugs, wires, cap, rotor, rebuilt the center carb (I plan to do the outboard carbs this fall). i've adjust float levels on all 3 carbs and set fuel mixture screws on center and front carb ( can't do the rear without taking it off the car, so that'll happen when I do the rebuild).
I've adjusted timing to what I think is about 15 degrees BTDC.
It will now idle around 900 RPM but there is a bit of surging when driving and some hesitation.
I can't tell if there is a miss but it's not very smooth and this engine/exhaust combination is so loud it's really hard to hear anything when driving over the exhaust(it's setup AAR style with side exhaust) and i'm pretty sure a big exhaust leak
I have a video of it idling so you all can hear what it sounds like: VLIX
