I don't know the numbers off hand, but I am sure Ron at Vengeance would be more then happy to give you the specifics.

A little tired man, but I just re read your post. Again I don't have specifics but if you look at the graph its obvious where the 402 needed more flow. In comparison to the TFS 215's the afr 205's were done at 4000 or so RPMS. So you want to dump the afr 225 for tfs 235 ?? I would think you'd want to bump compression up too, to take advantage of the increased flow. 225's from AFR and 235's from TFS flow great numbers while maintaining massive port velocity. Bump your compression and hold your torque numbers all the while raising your HP numbers. Best of luck and thanks for the nod on my combo. Couldn't have done it without the great guys at Vengeance Racing going the extra mile to make my project a success.
