Re: increase in HP?

you can get shorty headers and make a custom y pipe that will connect to your existing exhaust system.
the 416 HO heads will be a improvment over the swirl port heads.do some port work and it will be even better. the performer intake is a good street intake.if you get a bigger TB you should get bigger injectors . and a new tune will be a must
so some gains are to be made.
