I was wondering if anyone out there knew what the stock lt1 heads flow? Also if anyone knows of a chart or some kind of mathimatical problem that i can use in order to figure out cfm, when it involves ports and ccs and things like that. Im trying to figure out if the stock 170 ccs is enough for 6000 rpm. Is there a mathimatical chart or something i can refer to so i can do the math? thanks, any info is usuful.
