My car came with 30# injectors in it. I figured they were a little too big before I even heard it run. It is a .040 over 302... has ported and polished '69 model 351 heads, unknown camshaft, ported and welded intake manifold, 75mm TB, full exhaust, roller rockers. It runs strong, but puts out a lot of smoke at WOT. Will it do any damage to keep these injectors in my car, or should i just swap the sampling tube and drop in 24# injectors? The smoke it puts out is ridiculous at 6000rpm.
