450-500HP 360?

Honestly just have always wanted a car with 500hp. I would eventually like to have a 10 second street car. I should have plenty of time for the build since I have a good runner now and a spare engine and trans. Basically what I see here is that with a good set of heads and the right cam it should get me close.

And convertor.Very key piece.
If I was building a 10 sec small block street car( and I have lots of times, lol) I would start off with cubic inches. It’s gonna give you room to not get a combo perfect, but still run the numbers you are wanting to see. You also won’t have to lean on it rpm wise to get there.
It’s gonna typically be 3 or 4 tenths faster than a stock stroke deal, all else being similar. I just saw that going from a 360 myself , actually more, but also more compression.
