I have one (270S Comp) in my .060" over 318 (328") with modified "302" heads (360 valves, gasket matching, deshrouding, milling, etc.) and it runs fantastic! Used #901 Comp springs and stock 273 valve gear. Idles at 750rpm with a great little lope, pulls maybe 14"hg vacuum with a 625 Street Demon and Street Dominator small port intake. Used 2.5" collector long tube headers with a Flowmaster merge Y-pipe and a single 3" FlowTech Afterburner muffler and tailpipe. Gets 20mpg with an 833 O/D gearbox and 3.55 gears on the highway, too. Should be really mild in any 360 and work nice even with dished pistons.
