my guess is somewhere between 300-400 but does anyone have a better guess? its a car 390 from a 63 thunderbird with 9.5 to 1 cr. performer rpm intake. edelbrock 600 carb. k&n air filter. cloyes strait up timing gear set. comp cams 268h camshaft. hedman headers with 2.5 inch exhaust and glasspacks and msd ignition system. anyone with a similar engine build know there hp? its got plenty of power but i was just curious if someone had an actual hp number. i hate when people ask me about the hp and all i can say is i dunno
i don't have 1/4 mile times to use that calculator i was hoping maybe someone had the factory horsepower numbers. i figure if i added about 60-70 to that number id have a pretty good estimate of my horsepower.
