460 VS 501 CID
I'm beginning the build of the replacement engine for my 88 f250 (460efi c6/w205 t case) that burns oil like no other. The engine in question will be about 10:1 compression regardless of displacement chosen, d0ve-a block .030 over, D3 heads (stock valves, warmed over exhaust port), headers, and a lunati cam at 219/227 @050 540/552 lift 110* lobe separation.
I will be using edelbrocks pro flo 4 efi on it and gutting every piece of smog crap and factory efi on the truck.
The crankshaft I will be using needs turned anyway and I don't trust 50 year old rods, so I thought about having it offset ground to 4.14 stroke and just building it to a 501.
So my question is this, is the extra 40 cubes worth it for a simple truck engine? How would it perform compared to a 460 in mpg, torque, ect...?
