Re: Intake question for the engine guru's....

I have the performer RPM on my 67 an would really like to swap out to a perfromer just to see the diffirence. I would like more bottom end power because all the driving I do needs the get go. I also am not very happy with the millage I am getting (12 MPG with a 700R). It's a basic 355 using the 327/350HP cam I thinkit's a 447/447 lift. Thinking it's time to try the swap.
