Running Slant 6 225 for 76 Duster

Need a 225 motor for my 1976 Duster Project

I already have a good manual tranny, carb, intakes, etc.

MOTOR NEEDS TO BE A SOLID-RUNNING PULL ... preferably recent rebuild.

NEED TO VERIFY IT WILL mate-up with my 1976 Duster manual trans

WILL PAY CASH ... everyone knows what the fresh rebuilds cost retail ... I will pay any reasonable amount for a motor that I can verify is good and compatible.

PM please. Thanks.
