Mild 340 upgrade ideas?

Honestly if you're a student and work a part time job then wait until you're done with school and have the funding to do it right. If it runs good and is getting you by then leave it alone.

Secondly a 0.060 over 340 is a block I would not boost unless you have sonic checked the walls.
That's an entirely valid point I hadn't thought of. I'll stick to n/a and turbo my slant 6 instead for another car.
