Porting

[Kevin R.]

When one ports his stock intake do they do the upper and lower? Or can you just do the upper?

Thanks.

Take a look at www.tmossporting.com, he seems to know very well what he does, and thanks to his article, I´m going to port my lower Cobra intake, instead of buying another intake to go along my brand new AFR165 heads. (The money saved will bew spent on lt´s).

For stock heads, do the lower - no need really to do the upper - it flows ~50cfm more average.

Thanks that's all I needed.

Hey Tom, thanks for the info on your site, my friends were amazed too . In my setup, would you recomend some upper porting too? What work would you suggest?
Thanks for sharing your knowledge

No need to touch the upper (or lower really - unless it's to balance the the #1 & #5 runners) in my opinion.
