best intake?

Best intake for what? To sit there and look at or actually run good? What are you gonna do with the car? The Air Gap aint the only intake in the world, nor is it the best for every application.

It might be best for you but without a complete question how do we know? All we know is you have a 340 block and heads. I think you need more parts before you worry about an intake.

LOL.....:cheers: Every component matters and needs to match. If it is completely stock long block, that cast intake will be hard to beat! I once did a test on a 360. It was a pretty baseline motor save 9 to 1 pistons, and a mild MP cam with headers. I removed the cast intake and TQ for a LD340 and 750 dp. I gained exactly .15 in the 1/4. I brought with me a 625 carter AFB. I bolted that on and lost a tenth. I take it the 750 dp was running a little richer and thus the reason it outperformed the TQ and carter.
