What part of the intake are you interested in?

As far as HP goes I don't have a proper baseline impression, the system was installed when the car was restored and the engine was modified from the ground up. I can say this, it no longer suffers from any vapor lock or fuel starvation from cornering/braking forces and overall drivability has been much improved. Just like the news cars, you can start it outside the car from an open window and it fires and runs without any throttle input at fast idle. When warmed up it automatically settles down to normal idle speed.

check out the intake on the car in this video, no hood clearance required.

I wonder if the flex-jection system would fit... it uses a mechanical fuel pump instead of an electric so there's less hassel. www.rochesterproducts.com

I just took a measure. I have 6.75 inches from the top of the manifold to the underside of the hood. This sees like a tight fit. I use a drop air cleaner base on my demon and use a 2.5 inch air cleaner. This gives me 1/2 inch clearance with the hood closed. May have to use a thinner air cleaner to gain extra room.

I read there was not much difference between the torker manifold and the stock manifold in performance, if I do not need to change it that would be one less thing to do
is the torker manifold actually a lower rise than the stock '71 454 manifold? doesn't seem like it could be. but with the torker you could get it with the square bore pattern and eliminate the adapter.
