Is there enough material to remove on our intakes to install a 75mm t/b?

My 11.96 package (http://www.andersonfordmotorsport.com/cars/Marnold-302.html) had a 75mm on the factory intake.

cobra0393 said:Keep us informed on how it runs. I bet that cam works good with that combo.
9 deuce gt said:I have been thinking about this for a while, and your thread has spurred more thought. Here's how I see it, and this is in no way dissing your combo or future plans. As a matter of fact, I am hoping you can shed some light on this subject for me.
Afr 165's flow around 250 cfm. The Cobra when mildly ported can flow the same 250 cfm. This seems like a perfect match. Now, if you were to put a Holley or other intake (heavily ported Cobra) that can flow, say 300 cfm on the same 165's that only 250 cfm, would you get more power? Wouldn't the heads have to be ported as well?
9 deuce gt said:What I am getting at here, is are you sure 75mm T/B will perform better than the stock 65mm T/B? I would think the rest of the combo would have to match the flow characteristics of the 75mm T/B. (your combo may, I am just using it as a reference)
9 deuce gt said:Thanks for the response Lee. Yes, the cam plays an important role. With the Cobra and AFR 165 combo, I would think you would want a cam that has a lift of around .500 and a duration that favored the low end.
It would seem that a cam that could make use of the 75mm T/B would not be a good match for the Cobra/Afr combo, because it would most likely make it's power in the higher RPMs.
I am not down grading your combo, I am just trying to learn something here. And I appreciate your responses.
