is there a big diffference between 70mm and 75mm throotle bodys?for airflow i currently have a bbk cai with granetelli 75mm mass air matched to #24 lbs injectors,edelbrock performer upper and lower intake and dont plan on making more than 330hp being my goal is 280-300hp

i hear if i do 75mm all the way ill be losing torque for hp? but 70mm to 75mm i really dont believe it fact or fiction?

i honestly feel more power troughout the rpm with the 75mm mass air when compared to stock so adding the 75mm tb is icing on the cake right?

you wont be making enough power for a 75mm. 70mm is more then adequate for your goal

70mm will work for that intake manifold

I have 75mm but ALOT more mods and better intake manifold
