Generation IV External Engine - Whats the best flowing intake for L92 cylinder heads

Im doing a 6.0L swap and putting on L92 cylinder heads and was wondering whats the best stock intake manifold to put on.

ls3 unless you like to spend a lot of money on a fast

Hows the flow comparison between the L76 and LS3 intake?

L76 and LS3 intakes are the same, other than how the MAP sensor mounts.

Then why are the ls3 intakes demanding more money?

Spend a few extra dollars and get the holley hi-ram if you can get it to fit.

Hey westtexas, do you know if the holley high ram will fit under my ws6 glastek hood? Or maybe the edelbrock?

Then why are the ls3 intakes demanding more money?



I don't know...there's a few other subtle differences too, but bottom line is they flow the same.http://ls1tech.com/forums/generation-iv-external-engine/1502156-difference-between-l76-ls3-intake-manifolds.html

OP, I see the Z71 in your SN...are you putting this 6.0 in a truck? If so I'd run the L92 truck intake, it'll make more tq lower in the powerband compared to the car intakes.

I've had great luck with the Holley Hi Ram intakes

Hey westtexas, do you know if the holley high ram will fit under my ws6 glastek hood? Or maybe the edelbrock?It will take a lot of cutting, but yes you can get it to fit. Cowl will have to be cut, windshield wipers deleted, and the hood has to be cut to clear the stock WS6 hood. The pro flow is about the same.

Then why are the ls3 intakes demanding more money?

Because they come off Camaros or Corvettes as apposed to a truck.

Same reason most LS2s from a Corvette is more expensive than say one from GTO or TBSS.

An LS9 "intake" will "flow" best. :)

Thanks everybody for the input. Does anyone have any dyno test for any of the intakes. im goin to look for some in the threads.
