I am almost finished building an LA 360 that will go in a 73 Plymouth Duster Automatic. Here's the story so far... The duster is an original slant six, bought for a fairly decent price. I went searching for an engine for it and found a 76 Dodge 1 Ton Van with the 360. We pulled it out, Rebuilt it, had it bored .30 over, decked, chamfered, honed, the whole nine yards. We had the piston rods resized, and shaved .10 off of the crank.
