I bought a 440 out of a 78 camper last summer . 45 thou miles.
I tore it apart a month ago.
I found regular con rods. Also found
the cylinders to be like new.
452 heads with next to none wear in the guides.
I swapped the pistons for stock bore 6 pack speed pros. I weighed them and cant remember the exact weights but they were very close to the originals.
The original bearings were like new but I put new ones in.
Also put a magnum/ super commando purple shaft in it.
Plan to run the 452's for now.
I am having the truck 727 rebuilt . Swapping in a long tail housing and shaft.
I'm lookin forward to see how it turns out. I guess I need to decide what I'm putting it in first
