    That looks nice. I was looking into it later on. Let us know on how it runs on the car. Try to get some dyno numbers before and after if you can.

    I'm thinking there probably wont be very big gains over a standard LT4 intake setup, but these are undoubtedly easier to find than an LT4 manifold. The best setup is a still a single plane setup with a central top mounted throttle body.

    When it comes to power gains with certain mods i'm stupid. What are the average gains for the LT4 intake, and what are the average gains for the single plain and central top, and where can you find that setup? Like I said I'm stupid when it comes to the mods.

    The intake setup I'm talking about is for when you get really stupid with the power. Most guys have no need to go to such a setup. Putting a single plane setup on any LT1 with factory heads is a waste. I wouldnt bother with a single plane setup. Putting this manifold on an otherwise stock (or bolt on perhaps) LT1 (with possible required port matching to the heads) IMO might yield 10 or so horsepower, possibly a bit more on a built motor.

    yep he it right! not much hp for the stockers. remebber you have to put lt4 heads on there too, or the intake will not match up perfectly. im getting new heads and a huge cam. since i no longer drive this car everyday. im looking for a 110-130hp extra in the engine. but remember im far from stock. this item ran me $475 to the door and is set up for a 58mm tb. best advice is to know all your mod up fromt and plan them out. by the way im going to be selling my ported intake, ported heads, and mild cam if any one wants some cheap hp gains. i only have 4k miles on the cam.

    You do know that the LT4 manifold will not match up with the ports on the LT1 heads, right? The turbulence youll see with the extra lip on top/bottom will probably reduce the hp more then a stock LT1 manifold will.
