I'll be posting engine dyno numbers soon with that same intake on an LS7.

If I was going to spend 50k on a motor I think I'd go for a Nelson Racing Engine Twin Turbo 454 LSX motor that came in at 1500 hp/tq on street gas (2500hp on race gas) for 52k:

Or I could save a bunch of cash and only get their street mannered model and settle for 900 hp/tq for only 28k:

Or you could buy a supercharged LS9 and have $20k left over. lol


I'm sure it's nice but $50k for an engine makes me dizzy...

Out of curiosity, what does it take (parts wise) to build a 500ci LS motor? I wonder what block they're using? What heads and how much work have they had done to support that displacement?
