Ideas on 360 build

Find a good running 360 magnum 93-02, install bolt-ons & have the cam re-ground from bullet cams, alittle gear & stall & you should see low 13s easy, I have a 71 dart thats about 3200 with me & pulls off 12.5s through the mufflers. It has a stock bottom end, RHS heads, Air-gap intake, 650dp, summit headers/mufflers, 904 with a 2800 11" converter, 3.73 gears, i shift at 5100 & it has 17 inches manifold vacuum, i drive it everywhere, its a gas hogg. Theres no doubt i could install 3.55s to make it more highway compatable & still run 12s. It also runs great on 87 octane.
