critique this Magnum hop up, swap.

Thanks guys. This car will be a street Rod for 95 percent of its' use, so I do want to stick with some conservative choices, like
the 3.55 gears , reasonably tight converter and dual plane intake. The good part is it is a 2Dr coupe, and probably around 3,250 lbs with me in it. According to the Wallace hp calculator it will take about 400 dyno hp to go 12.00 given the elevation and weather in MN. If I need to put any $$ into the heads it will get a set of EQs which ought to do it.
