Not trying to hijack the thread sorry. If ford built the bottom ends on the new eco boost engines like they did on the 80's 5.0 it would be a decent set up. That would mean forged steal crank, HD forged rods and forged pistons and chain driven cams. I can't believe they ( not necessarily ford ) ever came out with those freaking engine exploding belt driven timing belts. If they snapped they would take out half the motor. Chains stretch and need replacing but the 80's 5.0 had a double roller timing chain. Possibly one of the stoutest engines ever to come off the assembly line. The late 90 and early 2000 Cobra motors had the same treatment. Different DOHC set up but done right. If the Eco Boost has all the mentioned motor upgrades then that would be a contender but if not then the V8 would have to my only choice.
