That is bolt on LS3 numbers. That motor is suffering with that combo.

My LS2 with LS3 heads/intake with a Tooley 229/244 is making 488 at the tire.....

Crazy that Lazers Stock H/C LS3 makes damn near the same power as most Cam LS3 cars. Goes to show there are plenty of other areas to make power before touching the cam on that engine.

I picked up a stock bottom end LS3 yesterday, and a set of TFS 255 heads. Trying to decide if the Fast 102 is worth the $ over the stock LS3 intake or not...That's a big diff in price for not too many more horses...Im prob going to go with TSP Stage 2 cam at 229/244 .629"/.615...Hopefully that cam wont have any PTV issues....

F-body rwhp will always read lower than vettes given on the same exact combo....

Example- A LS7 427 ZO6 making 600 rwhp... take the motor out the vette and put it in a camaro/firebird the 600 rwhp magic number will not show up.

I agree with you on the lacking . I was just showing the difference going from a ls6 to a ls3 bottom end with no other changes. The headers are 1 3/4 and a stock ls6 intake and throttle body.

A schmedium cam, badass heads and a stock intake is a serious mismatch of parts.

A mid length runner fast will offer another 1000+ rpm of power band, higher peak power rpm, and way more average power. above 5500 rpm.

A cam that large doesn't even come into tune until ~4500 rpm.

Me and Hiossilver built this combo in 2 cars A being my 2015 1LE with electric power steering and B being my c6 with power steering but i had a crank scraper and ATI on the C6. Numbers on same dyno are with in a few horsepower and torque so debunked as far as the C6 is magically 4% more efficient. Plus once you lose that initial % it does not continue to infinity at some point the loss is mute. If it only takes 60HP loss through the drivetrain at 1000 HP is it going to take 300? No.

If you haven't purchased a camshaft yet, we have two GREAT grinds that would work with your application quite well, and on sale for $349.99 right now We also have all other supporting valvetrain components, gaskets, etc you would need for the install.

I offer our Kaotik grind (235/243 .621/.624 113+2) or our bigger VRSP-3 (239/247 .624/.624 114+4). The Kaotik has been proven to make upwards of 490-500rwhp on manual C6 cars with STOCK heads/intake manifolds/throttle bodies on ours and other dynos, and the SP-3 will make a bit more peak RPM power and a heavier idle if you're looking for something more max-effort. The Kaotik is a NICE driver in the LS3 and with your TFS heads would be a solid street combo with great power delivery.

Here's some links for both. Feel free to call or e-mail me if you have any questions at all on either of these or any other parts for your build!
