well i finally got to take some measurements with a caliper i bought last night and it is a standard bore block! so i can get 2 rebuilds out of it so long as the block is useable and i believe it is. i plan on getting a dial bore gauge set but the caliper will do for now since i was just checking to see what the bore size was. i havent measured the crank yet and i'll probably do that today but i may just go with an aftermarket crank with cross drilled mains. i found a scat crank in cast steel for under 200 bucks.
in the mean time i'm still removing casting flash and smoothing the outside of the block. after doing this to my new thermostat housing for my 3.8 (cast iron) and painting it, it looks way better than it did before. so i'm hoping the block will look really nice and smooth when i get done with it. the front is done though i havent done the surface behind the timing chain cover, i want to finish the outside first.
i also have a question, can i do the same thing with the inside of the lifter gallery? i thought instead of painting it i would just smooth it out real fine. or is this a bad idea?
