Grumpy, Can you tell me the rpm flow rate of this intake? The gmpp intake # 12486570 I cant seem to find out anything about it except that it will fit vortec heads I was hoping to get to use it on 388. thanks
I would not, bet heavy amounts of cash on this, but I vaugely remember, reading some place that intake flows about 220-230cfm depending on the runner tested in AS CAST form, naturally porting can raise the numbers
