Let's talk 318/349/390 strokers.

I want to build one on the cheap and turn my stock looking 65 Barracuda into a sleeper that can handle the twisties. I have all of the parts laying around. 68 318 short block, magnum short block, set of 1.88 J heads and a couple of 360 cranks. I am thinking about using the magnum block and go with a roller to help with idle issues.(Edit: I forgot that magnum block wont work with the LA heads Duh)

I have heard that you can turn down a 360 crank to 318 mains and make 390 cubes? What rods and pistons do you use? I would like to start collecting parts that I need and get it to the machine shop.

Post your combos.
