440 six pack high idle

K.O. SWINGER said

To say that Mopar six packs must have promax plates is ridiculous there is hundreds of beautifully tuned six pack that have been raced to the top of their divisions or brackets and perform beautifully on the street without those plates and to slander all of them by calling them shade tree mechanics. Wow

When you have better options out there you might as well use them. Factory plates that have been tuned/modified cannot be tuned back to factory because you are physically removing material, so it will never run correctly. At least not from engine to engine. You have no idea what kind of engine they were modified for.

You’re right its not fair to call them all shade tree mechanics. But it wouldn’t matter if it was me or one of the ram charger guys, if you modify these plates there’s no turning back. With the promax plates you can jet up or down until its right for you. Just a quality of life suggestion.
