318 with 360 heads and compcam build help

Welp aren't getting anything decent these days in an A body for cheap. The time for cheap was late 80s early 90s...last Duster I looked at in summer of 2019 had a 318 auto rusty Lf frame rail rot and no interior but it ran and I could have drove it away. I offered the kid 3800 he said nope go kick rocks he wanted 5 if it weren't for the frame rot i would have done it.
