Where did you get 450 HP. Didn't watch all the way to the end, but got close enough.
I can tell you that I don't tune like Nick. No way on Gods green earth was 34 total optimal with that head and the junk plug location. That thing should have been at 38 minimum. So there's that.
Then there is the cam timing issue. He didn't change the cam for the headers, and since the customer wanted manifolds the cam should have been ground for that. So it's dead wrong for headers. I'm betting that cam was on a 112 LSA and that is a header killer and helps exhaust manifolds.
I always like watching Nicks videos. He must pay a ton of money for all that editing, unless he's good at it.
