Not sure this intake will feed 600 hp

Am I missing something? He says he's building a 408 stroker using Edelbrock magnum heads. That intake won't even bolt on?!?

It’ll bolt on…. With the use of a drill and tap on the head….

Port alignment is another issue. There isn’t enough aluminum to port match it to the stock window on the head. Maxing out the intake window area is the best that can be done at that area. It will help a lot.
