Small block supercharger setups
I could check but I think its 18 inches from the China wall to the top of the carb plate. Then a 1 inch riser is needed for the linkage, then the height of your carbs plus what ever hat you want.
So it's not fitting under a stock hood. If that's was your asking.
Cost?
Oh man, just take all your spending cash and put it in a bucket. When it fills up, throw the bucket at your car and repeat.
I'd say 30+ grand should get you a trans, rearend and short block that can handle it.
It can be done for less but I have no idea what you have or can do.
