'85 F150 power hopup
 

Would like some ideas on incresing the power of my 302 "underpowered" 4X4. It has a stick, but on the highway it is lacking in get-up-and-GO. What I am considering, is putting on some older 351W heads, a mild cam setup for lower RPM torque. Now, shall I go with higher compression pistons, or a turbocharger (which I have from a 351W)? Should I keep the stock manifold and fuel injection, or should I bolt on an aluminum high rise and holley 650 (which I have)? What about the stock distributor? Thanks
