Cheap-ish 360 mods

I don't know it's my opinion that a true budget build doesn't need Springs. Especially when it's strictly a street machine. You're not going to do some radical high-lift cam anyways you just want a little more Bang and that ain't going to snap Springs or you're not trying to eke out every last hundred on the Dragstrip.
Bad advice
The engine is 27 years old with how many miles?!?!
New cam = new springs = long dependable life.
