Description:

2011 LS3 intake internal support towers removed and radius "tubing" as opposed to rods cause the rear cylinders run leaner do to better breathing so using the tubing additional air is routed true for the front four cylinders to help the fronts, used with a llsr cam my stock block LS3 went 10.5 all day on it's first track outing and later dropped two tens with a higher 3800 stall and 26" tires.

Only reason I'm selling it is after 3.5 years the short block went south so upgrading to an LS7

The heads where milled quite a bit so the intake had its sides true to the milled heads so it will sit lower on a non milled set of heads this is remedy by using a one piece LS3 intake gasket on each side.

Full disclosure some intake gaskets inner support had to be reinforced to keep in place this doesn't affect performance it insures gasket retention and is the reason for such low price it happened when it was port match to the Trick Flow 255 cc LS3 heads. $350. Shipped
