The entire thread was strictly N/A so as long as you are N/A take what Accufab is telling you, they could not get more air passed the EGR (94/95) then what the stocker could get by. When you go blown then upgrade as your induction system can not swallow 845 CFM from a 75mm tb n/a. If you want a custom cam you would go to Jay Allen, Ed Curtis for motors folks like Ronnie Crawford, CHP, DSS for a tb info I would go with Accufab. In other words go by what a pro says in their own field says as they have more in depth info then some one who isn't. Accufab live and breathes TB not a custom cam grinder or engine builder. AFR knows their heads better then Ed Curtis so if a vendor is telling you one thing and the manufacture is telling you that info is false, who would you believe??
