I am working on a friends car and we are discussing the use of the cast aluminum intakes with the 90* elbos that everyone is using. I have seen them on most radical FI cas and a few other applications. I was wanting to know how they compare to the fast 90/90 setups and it also would be street driven and a 427. So just wanted to get some opinions and experiences you may have had etc...

So you are saying that they don't perform as well even when still using fuel injection? I am hearing mixed reviews on this have any experience or proof of either?
