Y pipe 3" or smaller on a 418" choking you Big Time!
Could be 30+ RWHP going to the right 3.5-4" Y!

You need true duals so that 418 can breathe.

. As expected since I saw my cats turned out NOT to be clogged. It gained 4hp up top, BUT in mid 3k rpms she picked up 16hp!!! Sooo all in all 489/486. Im happy. My tuner got her running much smoother than before. A cam my size, with my power and I can roll in 4th gear at 35-37mph and just as smooth as butter

Decided not to port the intake. I mean I know Id see the 500 and probably not much over it. Not gona chase numbers. Car feels awesome!!! Saw 6th gear for a few minutes today around 75mph and she manages 23-25mpg. Ill take it!!!!

Glad to see it picked up through out the curve. Your cam is not big for that motor and it should have great drivability. The only real way to gain on the top end is going to be with a bigger intake and throttle body so you always have that option down the road when you get use to it and say to yourself time for some more upgrades
