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.
