LS3 heads were ordered today for the GMC, LS3 heads feature sodium filled valves and upgraded springs and are identical to L92 Heads otherwise. The list consist of L92 intake manifold, nick williams 92mm TB Ls3 heads and reusing my 214/218 cam, its a good all around truck cam.
I will see what this combo makes for power, I hope it is good.
I am saving my Old Lq9 heads for my Lq4 Shortblock. That Lq4 is going in a 65 Lemans convertible for my dad rebuilding it soon. Its the old motor out of my truck, were giving a second lease on life, as a fun motor and not a work horse.
Port the Lq9 heads and LS2 manifold, 92mm Nick Williams throttle body, 224/230 grind cam on a 114LSA, not sure what i am going to do with the bottom end.
