what size thottle body would suit my Stang, my mods are in my sig cept yesturday i added a MSD Ignition, i was thinkin 70mm but maybe im wrong so any help would be nice

I would suggest a 65mm , unless you plan on doing major engine work in the near future, get a 65 mm TB and a 73-76 mm mass air meter, that will really open it up.

i dont have maf, would a 70mm thottle body hurt me more than help or, i may build the engine up more in college because im goin to a high performance engine school, so would it be safe to buy a 70mm just incase i do an engine build and not worry about buyin another 1

With the mods that you have go for the 65 mm!!! 70 will be to big

Iv been told by the big guys on here, dont go to large it will hurt your car no help it.
I would get a 65mm and get a mass air conversion , your gonna need it sooner or later.
