I am new here, I am thinking about swapping out my 322 and dynaflow tranny with a rebuilt 401 nailhead. What transmission would I need to go with the 401 to make it a 4-speed? Would I need to do anything to current drive train or rear end to make this happen. What about modifications to the stock gauges? My 322 and dynaflow work fine, just minor leaks. But, I compete in the modified class of car shows and am tired of getting beat by those crate engines. So, I am looking to get a boost in horsepower and have some cosmetic upgrades too. My 322 has a 4 barrel and I run a dual exhaust. Any advice is greatly appreciated.

Thanks,

Mark
