I'd have to say though that the E-brock dual plane is a big improvement over the stock manifold. They're good right off the line. I had one on my '68 Skylark and I used to get 18+ MPG driving the 405 past LAX every day for years. That was with a mild cam and a 1406 E-brock carburetor. If I ever go through my truck engine, it'll get an E-brock intake, but I'll keep the Q-Jet, in this case.
