i think about385to 395 flywheel hp x .88 for losses=347 rear wheel and a bigger carb won't make any more. this should show as 11.54 @117.2. so add a sec for street tires and might do 12.5 or less w driving skill, but the mph will tell you rear wheel hp. i ran a 472 ci (.60 over) 460 w a 284 .486 110 lobe cam and heavily ported d0ve heads w big valves, 2 inch headers,830 dp holly. and saw an average 11.7 @ 119 in a 2600 lb cobra, and all this was done w a stock cleaned up 460 non cj intake and a 5800 red line, 2.5 rear end gears (each shift takes between .2 to .4 of a sec) good enough to go neck and neck with a 650 kawasaki, on street tires, you gotta love big blocks!!!
