'74 Duster big block conversion
Engine update - I got the 440 torn down. The tops of the cylinders were ground on, I guess for valve clearance, but on the lower side of the cylinders. That would match the upside down pistons. Rod side clearance is huge, over .035 on rods 7/8 and 3/4. The sides of the rods were ground on possibly for balance? .020 of end play on the crankshaft. I'm just going to play taps over this poor thing and move on.
I have a low mileage .030 over 383 that I have been holding onto. I pulled it out of storage and am going to go through it for Duster.
