I would like to tighten the converter and run a taller rear gear to drop rpm and increase the throttle response. I just don't care for a "loose" feeling setup in a street driver. As far as how much stroke i want, it would be what ever i can put together for a modest price, like under a grand for the crank. I see there are already 4.25 cranks, just curious how far this can be taken and in a price range not a lot above an off the shelf stroker kit.
