Engine: 1990 305, 906 vortecs, factory roller cam, Q-jet carb, Factory exhaust, daily driver. Vehicle: 1980 B-body (caprice), 200 4r, 3.08 gears, 215/70R15 tires.
My intake choices were between edebrock, professional products, or GM performance. I searched this same question and no one had anything good to say about the professional product intake. Eveyone was saying they are cheap chinese junk so I eliminated that one right away. I couldn't find any coments on the GM performance vs the edelbrock. I have seen some people talk about the exhaust crossover (which my vortec heads do not have) for cold weather starting. I don't know how important the crossover is but I don't mind if I have to let it warm up for a few minutes in the winter. Winters can get pretty cold in New England, the coldest I have seen was -10 for a few days. Anyways just wanted to know if anyone is familiar with the GM performance manifolds, it's about $140 more than the edelbrock but if it's a better manifold I don't mind paying for quality.
These are the links to both manifolds.
