Best performing factory GM intakes?

[67Nova421]

So I scored this L82 factory GM aluminum intake along with a standard bore 400 engine. Part # 14014432 from what I researched it's a L82 350 intake. Has anyone run this with good results? What are your favorite stock GM intakes to run for best performance? Thanks.

Don't know about that one, I do have a 4067053 aluminum intake very similar to that one if somebody needs it. Anybody?

Right after high school I had a 73 Corvette with the L-82. Replaced the 72 LT-1 in the Corvettes. What a turd. I think it had a 5800-factory red line. Still incorporated the 4-bolt block, but the Holley Carb was replaced with the Q-Jet (hence your manifold), the solid lifter cam was replaced with the old 68 350/350 HP hydraulic bumpstick. I think it had 993 heads.....

71/72 LT-1 Can use 993 heads also, but with 2.02 / 1.60 valves
