I am in need of a new converter behind my 511 and want to be just somewhat conservative, since the engine likely has a pretty flat torque curve. Being the larger converters are cheaper and generally tighter, I’m just wondering how well this converter would work in my combo. I do plan to upgrade heads at some point.
