Teenage budget build

My advice to you is make sure the car is safe first before you go into the engine build process.
That means, are the brakes, tires, front suspension, rust issues especially in the frames and structural areas of the car good?
If so, then build a engine within the budget you can really afford, tell us how much money we're looking at.
Don't fall for the stroker engine hype unless you have a lot of money.
I don't care what any one says, they are not cheap to build, even on a budget.
I would just refreshen/rebuild the 360.
