re: 454 street engine ??s
I'd guess around 375-390 H.P. if you have 1 3/4" primary headers and a properly curved ignition system. The larger carb may give slightly higher 'peak' HP numbers, but the carb you have now should give great drivability and accelleration.

Big limiting factor (the stock valves)... Open them up for the 2.19/.188 valves and it will breath a whole lot better... Also switching to the 750 speed demon with the larger valves will work great together...
