I would of liked for gm to had come with this engine sooner, they only upgraded the heads for the 6 bolt lsx and the crankshaft for the lsa they left the same connecting rods as in my engine they just changed the description to forged powder metal still same part number.
is still a better motor n would of bought this at the time if it was available
allen pm me with a ballpark of a tvs2300 install with a ls9 cam if you can, thanks
