I have a 440 in a e bod,lunati 303 cam,worked 452 heads,391 rear auto.
has 3/8 sender,fuel line,eddy mech. pump,eddy rpm intake,850 holly dbl. pumper msd 6a ign.,headers,2 1/2" exhaust. runs like a champ and falls apart just a tic past 5 grand. I've tried jetting,timing,fuel pumps,no air cleaner,gas cap,2 different dizzy's all with the exact same results.
I would think it should pull past 5 grand but cant figure what's hanging it up. seems to be fuel but plugs are a nice tan color.
Any idea's??? I'm stumped.
