I just bought a use IC and it is a front mount one.
My question is can I install it with the original nose and how much benefit would it give as far as hp.
Thank you

 

Without knowing all the specifics of the IC, there's really no way to tell you how much hp you'd get. Check out Spearco to try to compare your's to one of theirs. That'll at least point you in the right direction. Good luck.
