i was at the dealer the other day, my buddy in parts was showing me a new crate engine add, had a carb manifold, 6 bolt heads, looked like it was maybe built off L92 head platform or something, but was listed at over 500 HP, big cam also
he couldnt find a price from the part #, but my guess is $$$$$$$$$$$$$$$$
prob built from an LSX block for sure

 

probably was the lsx block i know that they are supposed to be coming out with 2 crate engines, one with around 5-550 and the other with around 700 i believe, not really 100% on the numbers but i know they are coming out with 2 lsx crate engines.
