318 Street/Strip build?

Oh man, there are so many directions to go here, but first:

What is your end goal?
What's your budget?
Have you researched some of the builds in here utilizing the search bar?

Plenty of ways to make a 318 run well, and in a 65 Val, a well built one will move it along smartly without breaking the bank, but you also need to take the REST OF THE CAR into consideration. Making a street/strip car is just as much, if not more, about the chassis, suspension, and braking as it is about power...having a powerful engine is nearly useless for time slips if you're not putting the power to the pavement, unless you enjoy making expensive clouds of smoke and tearing up suspension and driveline parts...
