Can you guys give me the flow numbers for the stock intakes or modified intakes and can you give me the runner dimensions? Im using an engine analyzer to see get a better idea of the original engines rated in net hp. I got 425 ft lbs @ 5 grand and 446 hp at 6000 rpms for the L78 with the head flow numbers and all of the cam info. I have everything correct except the intake, which I have a single plane intake with a 1.3 flow coefficient in use. I put in combos before that I knew the actual outcome for, and this thing under rated it.
