Stock block plus 2.000 sbc rods, longset stroke?

Just speculating. I am down with a back injury and too much time on my hands! If there is a crank core out there that could be ground on a bigger stroke for a somewhat reasonable price, it might be an interesting project. My 408 is a great motor, but even with the airgap dual plane and 235/249/107 duration cam make for the need of a looser converter than i like. The converter i have is a ten inch. A&A said it would be tight, but i would like a tighter converter yet and the only way to get that is all the cubes i can stuff in a stock block. The 408 would make a great ten second backup motor for my race car if I ever need it. Almost zero maintanace and no fire suit needed! Greg
If I'm understanding you correctly your looking at how the converter acts totally opposite of what it is. Big cubes = big torque. Big torque = more stall speed from the same converter which makes it feel looser
