Can't you buy the Mopar M1 w/ a spread bore? I'd think a 440 w/ a 1000 TQ would be a good running car.
Yes, the M1 has a spreadbore pattern but if anyone is going to tool up and make a new carb they are going to want to have it fit a maximum number of vehicles and spreadbores are in the minority.
440 runs great with a TQ, I campaigned for years with an 850 on a TM-7 with an adapter plate. Back on the shelf waiting to be used again on a different car now that the GTX is sporting the tunnel ram again.
Now that you mention it, spreadbores are none existent in CarterBrocks. Again they are the simpler carb with less choices for those that like that.
But Holley and their partners are making more and more carbs with dual patterns. Including the new Speed Demon.
