30s should be fine, 42s would work as well if you want to have some room to grow

svo 30's would be fine. being that they are rated on a ford fuel system. when used on a gm fuel system i believe they actually make like 32 lb/hr or something...somebody chime in with the specs. but that's what i am running and they are no where near maxed out. but if you want the middle ground there are 36 lb injectors too.
