Hey,I was wondering if theres kits you can buy that have a bunch of parts to make your engine better, camshaft, heads, intake manifold etc...

yes, of course, more info could point you in the right direction...

car,year,model,engine,known mods,you budget/expectations...

edelbrock makes kits, among other companies, just depends how much you want to spend. you can get complete hp kits including cam, heads, manifold, you can go even further, get a complete engine, like i said, mainly depends on $$
