Long time coming, but I'm building a little bracket car
Just to add a few more things - I think the pump gas or race gas question is pertinent here. Higher compression will make it easier to attain your goal. Pump gas is always a compromise. Run the highest C.R. your combo will allow if race gas is what you're using.
500 hp from 408 cubic inches is 1.2-1.3 hp/cubic inch. Tough to get there with a pump gas compression ratio. Again, good cylinder heads ($$$).
What is your budget like? Think you can build a low 11 second car for cheap? Not likely. $400 for the car is a pretty good start but that's gonna add up real quick. Makes my head hurt to think about how much money I spend on peripheral stuff like hoses and fittings, brakes, fuel system stuff, tires, etc. :mrgreen:
