It’s on baby, the intake test you have been wanting and needing! Is the L83 intake the best LT intake made? Or is the L86 better? Or does the bad boy MSD intake blow them both away and take the title as the best of the best? Or does the application and the size of the engine actually matter? Well Richard Holdener is the dude of dudes when it comes to testing engines, and especially intake manifolds, and he’s got a test here with all three intakes on a couple different combos so you can really see what each of them does in different scenarios. Of course if you watch all the way through you’ll see Richard’s conclusions, and have the ability to ask questions about what you are seeing.

Here’s the video description from Richard. It’s all CAPS cause he’s angry.
