Should I stick with my 65mm, go with 70 or even 75MM??? Your opinions are appreciated  THANKS! |
I have about the best flowing heads possible(Ported 192cc Canfields) with a ported cobra intake and a huge Ed Curtis .566 lift custom grind cam and my 65mm TB still isnt a bottle neck.
I borrowed a 70mm TB and it ran exactly the same.
Stick with the 65mm unless getting a bigger one will make you feel better somehow. 
The cobra intake will choke your engine way before the 65mm throttle body will.
