ok for cheap then, just get the solid .528 cam for the 383 & e85 quickfuel carb have the heads milled to get you to 12:1 or so (iron heads, alum could go to 13:1) run a 180 deg thermostat
you will probably want to run an elec fuel pump with return style regulator/bypass if you go E85
on straight pump gas, ok yeah the 360magnum might have an edge. just watch when you buy one though make sure the exhaust valve seats are not all cracked up. if it came out of a pickup, rode real hard they probably are.
