Intake Manifold Recommendation 74
I was wondering if anyone have a recommendation for a intake manifold for a 74.
1974' Corvette
Original base 350 engine (195hp?)
Rochester Quadra-Jet
4-Speed Manual
Factory Small Block Hood/Air Cleaner
I was was looking for a aluminum/polished aluminum intake manifold that would work well on the stock engine (only performance upgrade so far is a set of Doug's exhaust headers) as well perform well once I get around to rebuilding the internals (Would be using new Heads/Cams/ect). I would be willing to replace both the air cleaner as well as the carb to accommodate a larger intake manifold if that's happens to be the best solution.
I was recommended Weiand intake by a local shop, was wondering if anyone could suggest a particular model or a different intake all together?

Since you're pretty much stock, and won't see RPMs higher then 5500, I'd go with a performer intake. Once you upgrade the cam and heads you can go with a performer rpm, or whatever will work with your top end set up
. Rebuild, tune, and keep the quadrajet. You won't need anything bigger then that

If you're looking for more power, I think you may be disappointed. My recommendation would be to save your money until you can do something more serious, like better heads and a decent cam. Good heads like Vortecs or Edelbrock and a decent cam will wake up that sleeping 350.

I wasn't expecting much additional power out of just a intake and headers. The Headers were only upgraded because the existing manifolds were cracked and I figured it was better to spend the extra money on headers now then to replace the manifolds, then replace them with headers later.
The intake manifold is more of a aesthetic upgrade until I have the time to do a proper rebuild. Everything in the engine bay is basically rotted out, so iv been replacing broken items and refinishing others that are functional but a PIA to remove (Brake booster for example.). I'm repainting the engine block back to the original red/orange, and thought that a polished intake would really help finish the "clean" look. I'm actually shorter on time than I am on money, so it may be some time before I actually am able to do a entire internal build out (2+ years). I still have a factory AC system to pull, Vintage Air to install, an entire interior to gut and replace and considerable trim/exterior work. At this point, I'm just trying to clean up the look of the engine and scrape out a few extra ponies of possible with the intent of returning later to properly build out the engine.
