400 Non Stroker Build

Mine may goal is pump gas 93 octane is fine doesn’t have to be 87. And try to make this Cbody move a little with this 400 and be streetable. I will probably run at least 3:55 gears or lower. If I wanna go on a road trip will swap gears. I just wanna make sure the motor is not to radical where it can’t be driven etc.... So I think this will be a good build! Should have a lot more pep than the stock 383 2 barrel. Which for 71 only had 275 hp I think?
