Can't decide on what engine to go with in my '82 Fury - it's my daily driver and sees 50/50 city/highway driving. I beat on it hard, want the power and at least some semblance of fuel economy/ street manners. My 2 options: rebuild the LA 318 I have or go with an LA 360.

318 option: machine work (basic clean up, assembly and balancing) KB 167 pistons, lightweight con rods (Which ones?), Lunati Voodoo 256/262 cam, Magnum heads.

360 option: Machine work, same cam, performance torque converter for stock 904 OR 727, torque converter, driveshaft shortened.

Any thoughts? 4000# car and 2.94 gears
