Well, I have the hemi back in my 69 black RR. Custom 3000 stall, motor is 40 over with orig manifolds, mild cam, brand new restored orig carbs, new firecore wires, mopar electronic ign, electric and mech fuel pump with 10 psi at idle and 6 psi under full throttle. Car idles wonderful and rips the tires off from the line but it seems to break up (seems electrical) at about 3200 rpms when the pedal is to the floor. Seems to choke and it wont pull hard all the way. Im at my wits end.
