My uncle Tony was the original owner , I got it from him in 86ish had 75k on it then.
The only then 1975 about this truck are the frame, doors, fenders title and bedsides . This is the 2nd cab and it's a 85.
This poor truck has been molested, beaten, butchered caged then I got it.
The original 440 I think was yanked 2 weeks after the truck was brought home. My uncle Robbie wrecked his 70 GTX a week after Tony got the truck, so in went that 440 and 4speed.the org 727 has been out of the pitcher since 75, I couldn't even venture a guess as to where that is today , or if it still "is" the Dana that's in it now came from my uncle Tony 71 Challenger.
I have the org 440 in it now and an overdrive A833, so yes the 440 will still be around.
If this 75 was as original as my Midnite or Black and Green warlocks, I would of sold it a while ago, but the truck is so far removed from being original.
