I saw this Diplomat thumbing through a weekly auto sales ad yesterday. It's not like I need another project, but this thing got me thinking. It's a '85 with a 318 but according to the ad it has 'engine knock'. I assume the crank is probably trashed, but the block should be okay. Being an '85 it should have the 302 swirl heads on it. It has an automatic, I assume a 999 with lockup converter. What rear axle would it have, 8-1/4 maybe?

Hmmm, I have a spare 360 crank and set of 360 rods. I also have some 1.88 intake valves and an extra 4bbl intake. Ahhh, how about a stroked 318? This could make for an interesting sleeper/beater. What do you guys think?
