Hmmm..... Function as intended
Let's take the SD455 for example. One of the greatest engines to ever come out of Detroit. Guys at Pontiac started kicking around the idea in the late 60's and shortly after had the engineering department start developmental work. It started out with a cast crank, good rods and RAIV heads, it went through many changes including ported heads, BLOCKED EXHAUST CROSSOVERS, headers bigger camshaft, forged cranks and a Holley carburetor. Now it was turned over to the guys that had to figure out how to make the engine profitable. Head flow was reduced, compression lowered, camshaft tamed and a cast crank replaced the forged unit. Now the EPA guys had to make it pass emissions so the cam was tamed further, an EGR system was added and the hood scoop sealed up.
So fast forward to 2026 and you want to build your own Super Duty engine, which version will "function as intended"?
