box type upper intake

Hello, Can someone please tell me if I would benefit from installing a polymer box upper intake onto a 5.0??? Would I get more power?? thanks

By replacing the upper intake with a 'box', you shorten the intake runners. By shortening the runners, you move power up to a higher rpm range. Unless it's a race or high-rpm street engine, you would most likely be best off with a standard upper.
I think one of the recent FM articles talks about runner length on 5.0L engines, check it out.

Hello,
Thanks for the information. Would my acceleration be better or worst from stock??
