From ebay ad:

I have a Prototype LS1/LS3 intake manifold for sale. It is All ALUMINUM casting, with a 85mm throttle body opening that accepts LS1 3 bolt 85mm throttle bodies. (not the newer LS3 90mm throttle bodies)

LS1/LS2 map sensor in the rear of the manifold

LS3 intake ports so it will fit newer 6.0's, 6.2's and L92 heads

LS3 stainless fuel rail as well

There is no information on this intake what so ever. No casting numbers! I have contacted Livernois, Perfessional Products, Holley and a few other manufactures of this intake and they all say it must be a GM prototype.

It accepts LS2 style injectors but they are not included.



I purchased this as the seller told me it was an LS6 intake. Which it is not. So I am selling it to purchase a LS6 intake. I am willing to accept a LS6 intake on trade as long it is not cracked and it includes the rails and injectors.


This is NOT my auction and I DO NOT know the seller!

Don't really understand the use of the 3 bolt TB but different looking piece nonetheless... I wonder if it's maybe a catherdral intake with the port openings reshaped??
