A lot ! Man with the amount of air that engine demands , putting a fast 90/90 will do at least 30 more to the wheel than a ls1 intake on a 408 . Also you are talking about power under the curve not just top end .

I'm w/ snake charmer. You're looking at 25-30rwhp on a strong 408. You can also port and port match it for a bit more.





And you can drill/tap the fogger bosses for the direct port.....

I'd say like 500. jk But realy... alot. I would say at LEAST 30. Cause on that big of a motor, it would do 20 over an LS6. I guess depend alot of the heads as well.
