I have a new set of 440 mopar chrome headers, big tubes 2" or 2-1/8" not sure. Cost over $500.00. It is set up for a big block. I did have a 440 in it, but took it out to use the heads on another engine. That short block is fresh with Speedpro pistons, .509 hyd, cam, lightened & balanced rods. The 727 trans is still in the car and I have a 4000-4500 stall converter to go with it. $2000. for the 440 short block, trans and converter. Underhood pic is before it was painted. The paint is 4 coats of acrylic enamel. It needs to be color sanded and a final coat applied.
