You sure can mill LS3 heads... I did it. Did you mean that you can't mill LS3 heads and use an F35 cam without fly cutting? If so, then I agree. |

an auto c6 vette would hit 500 to the tire with this cam... well 498.6X which is splitting hairs in my opinion. the last 1.4 rwhp is for bragging rights only, and its so close i'd call it 500 rwhp anyway.
this is using a TSP engine dyno chart reading of 576.6 and a 15% drivetrain loss (which was done using a stock L99. TSP themselves said the recorded HP would have been +10 with an LS3) 586.6 x 15% gets you 87.99 loss. link for TSP chart: https://ls1tech.com/forums/generatio...-camshaft.html edit: i agree an L99 Camaro probably won't hit 500 rwhp but it should be within 485-495 depending on conditions

interesting... my calc definitely fails to consider how an engine will perform being in a car vs on an engine stand... good numbers though. what supporting mods were/are on the car?

I didn’t mean for the back and forth bickering lol but I appreciate all the input and I was just curious as to what everyone thought. Gpi is claiming 500hp out the l99s. Just curious to see the proof on a true dyno. I talked to them today about a heads and cam package, the cam being a ss3 and their heads which I want to say are 260cc heads and the guy I was talking to said I would see around 530 with that package I just can’t see it personally. Anybody does this package and can vouch for it?

If you're just chasing a dyno number just make sure you spend some time studying your local dyno options - you'll learn who has the "happiest" dyno.

Yes sir, it needed 4.30 gears. I had just not got to that point before it was totaled. Car went 11.56@120 Race weight was around 3640.
