Recently there was a member that uses the name Pray that had a 416 that made 573 at the wheels, probably the same guy. He had TFS 235, 12 to 1 compression. You can probably find it through the search.

Well I will stay NA. NO N20 or FI.
I have as cast Trickflow 220cc heads. I'm thinking along the lines of a 236/238 600ish cam. I have an A4. Want as much power as I can get while still ensuring I don't get any surging or bucking with the cam. I have to maintain good street manners.
Not sure I believe the 1.27/ci. That would mean I'd gain 50whp going from 364 to 403. I think most only gain around 17 with the same jump?

Go to Vengeance to get it tune. They take as long as it takes to make sure that the car is right.

I live in Texas man. GA is a hike.
I ordered a 416 through Va Speed. It was a hard choice and I had to do a lot of research to come to that decision. But I finally placed the order.

I'd like to see that car on another dyno. 427 C6 Z06's with ported LS7 heads, cam upgrades and exhaust work and a tune are having trouble making 570 RWHP. There are some that I've seen over 600, but most are in that 570-580 area.

That nothing. I drove over 1,200 mile one way from MN in a snow storm to make sure that my car will last and make the power it should. I did drive the camaro and when I got hour 1 1/2 out of St. louis my SLP loudmouth exhaust broke and I had to deal with open headers and y-pipe. That Fing sucked

I'd run the 416 over the LS2 based 402. It'll unshroud the valves more and allow a head like the TFS235 to make a little more power.
A mid 230s duration cam would be pretty mild in that size motor. A cam that would act "cammed" but still be extremely livable would be a mid 240s duration cam and would perform better.
