The valve covers are unbaffled Mopar performance anodized ones sitting on the fairly tall re-useable gaskets. I have the small bolt in moroso baffles but no signs of anything touching there.
All the valves where set to zero lash then 1/2 turn down from as per the builder. They also where done with the intake off the first time to insure being on the base circle of the cam.
As far as fuel pick up I dont run a stock pick up but a sump in my fuel tank with the large -3?? braided line all the nice AN fittings. Going to check my fuel filter though but the bowls always look to be sitting at their respective levels.
This same Demon was also on my 340 and has been checked, cleaned and certified before it hit my door step. The car will start on the first crank idles nicely and and speed runs great with good throtttle response. But WOT off the line if I keep it rugged up to about 2400-2500 rpm I feel like I should get out and push it just falls FLAT after that its a rocket.
I've tuned and retuned as per the instruction guide I was given with the same result great top end no wot off the line. I was told for my gear ratio, tire size etc this was the carb for me. The distributor is even curved to match the set up.
Moper I dont disagree with you at all I follow the KISS solotion here and aside from my TERRIBLE luck with this car -If it can be defective, late, wrong etc I got it-
This is why I was hoping to find an experianced Demon tuner to make sure I'm not missing the obvious. My dad was a hot rodder and muscle car guy from way back in the day and was really into it. He's forgotten a lot but still very good its just the Demon is so new to what he remembers as a Holly or TQ, Carter etc.
As far as the valve adjustment goes the man sets valve son multimillion dollar 280ton plus diesel dump trucks I figured between him and me a valve adjustment was a no brainer.
