As for the 360 crank I thought somone mentioned a 390 stroker on the other page and nobody got on him. The magnum heads come stock on 5.2 magnums so they would be allowed. As would a roller block 318 from the 80's or a magnum block for that matter. In fact let me change the formula to include a hydraulic roller cam seeing as there are plenty of factory roller cam blocks to be had...
In fact the starter of the thread mentioned using the same parts I did so dont get on me for it. Instead read the post,lol.
