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?

FryZ71

I don't know...there's a few other subtle differences too, but bottom line is they flow the same.https://ls1tech.com/forums/generatio...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

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.

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.
