There is alot you can do too a small block. The basic concept of ford n chevy r bout the same. Easy upgrades are cams, intake, distributor, carb. You can do Head work but depending on wut ur doing with the vehicle depends on the head work and how much its gona cost. If u hav fuel injection u can do pretty much the same stuff to it. If u got any more in detail questions jus let me knw. All i own r chevys.
