Intake Manifold Question
What aluminum intake manifold could I put on my bone stock 1971 350/270 that wouldn't cause clearance problems with the original Quadrajet and dual-snorkel air cleaner installed? I am not looking for a big horsepower increase, just better appearance as the orginal manifold has discolored due to the heat channel through the center of the manifold which looks terrible. Thanks!

I was told I could run the 2101 Performer or the Edelbrock EPS without problems. Don’t go on my say though; let some of the more knowledgeable guys give you their opinions first.
Good luck!

If you don't want to spend a lot of money and are satisfied with your current setup performance wise. pull the intake manifold clean it up repaint it and when you re-install it use an intake block off gasket to block the heat riser passage. old hot rodder trick. bythe way i think most of the aftermarket does not have the heat riser function. its to heat under the carb when cold to make the engine run smoother when cold start up.

Just visually comparing the ports on these they appear identical.

Swapmeets are best buys.

But at large swapmeets i have better luck as the intakes are already removed and can bargin for price. Now have plenty of Alum intakes (too many really) to play with and modify - 2 happen to be from late '70's vettes.
Happy hunting. cardo0
