2014 1le ls7 cam, ported heads, long tubes.

[Jmh_0711]

Hello everyone, I just ordered a few mods, I purchaced the cnc ported head and ls7 cam kit straight from gm, along with kooks long tube headers and hiflow cats, parts plus shipping I ended up paying about $3300 for everything, after labor and tune ill be around $5000, it will be finished by august 20th and ill have the dyno numbers for anyone who is interested!

5k? why not save up a bit more and go with a supercharger

Can't wait to see what the LS7 cam nets.

I have enough to go supercharger, even after these mods, but I like the thought of, alot of power with a naturally aspirated engine. I saw another 1le with similar mods dyno at 527 to the wheels, i havent seen many supercharger systems offer over 600 rwhp without supporting mods.

Not looking to start a fire storm , but if a 427 LS7 is good for 505 hp at the flywheel ( 475 rwhp )how can a 376 with a LS7 cam make 527 to the rear wheels ? Your numbers are way too optimistic . And IMHO there are a lot better cams out there to make big power . As far as I know LS7 heads are cnc ported too .

Im not claiming any gains of power until i have my own dyno sheets, I was just stating what I saw, a 2014 1le with ported heads and cam, cai, headers made 527rwhp. Like I said, ill post numbers in a few weeks.

Good luck.....please don't get your hopes up as I thought Chevy claims that the heads and cam are worth about 40hp..,(not 100% sure) 500rwhp is a lot for a na ls3. I bet 475ish rwhp when all is said and done. The highest hp na 1le I've seen is this one:http://www.camaro5.com/forums/showthread.php?t=411837 and the mods to it are not your common heads/ cam supporting mods car.
No matter what I'm sure it will run strong and it will be enjoyable but don't set your expectations too high because I've seen more then one dyno crush a person's ego or expectations.

475rwhp doesnt equate to 505bhp... Not even close. Most stock C6Zs dyno in the 430-450 range.

I'm entertaining this option. I was looking at twin turbos, but that is off the table. Im wanting to run a sustained speed of 150 MPH for Silvetstate. I talked with RMS here in Calif. about doing my heads, a cam, headers and a tune. They said 500 RWHP is in the ballpark.

Good luck and Lsa conversion will get you way past 600 rwhp mark

Not everybody wants the power of forced induction. Harsh torque curves are harder to manage on a twisty track or road course. The extra weight in general is again, a minus for anyone, but especially for anyone that want's to do more than just go fast straight.
It also produces power that puts strain to the limits of several other components on the car, namely clutch, diff, and halfshafts, but also on everything else. Even if people claim the bottom end can handle 700, 800, 900hp doesn't mean it was built to do so.
To truly, reliably run much more than 550-600 rwhp is going to cost way more than that $6-7k supercharger or $8k turbo 'bolt on' kit cost. I'd say that you have to just about double that cost.

Some people want that loppy, rough, mean idle and power curve that the right cam provides. And some of us don't want to have to go into the trans, rear end, fuel tank, etc. to gain more power.

If you're talking about the guy I think you're talking about, he may have made 527rwhp, but he had wayyy different heads(PRC255 heads), WAYYYYYYY different cam(TSP235/239), and what really got him to the 527rwhp(I mean, compared to say 500-510 on a happy dyno) was likely the FAST 102 intake and 102mm throttle body. But that horsepower from the intake came at the cost of not too much torque gain(only like 440rwtq, which is only about 20lb/in more torque compared to a bolt-on, tuned engine on a stock cam).
My guess, is you'll be more in the 460rwhp area...

no disrespect but that set up is going to be a big disapointment if you expect 527rwhp out of it ...and definatly don't dyno it on a load bearing dyno or your really gonna feel bad ..i have a decent setup with a much bigger cam and i make 484 434 on a mustang dyno ..good luck
a 427 with ls7 heads and ls7 cam make about 445-460 rwhp so doing that setup on a 376 is gonna be lower wouldn't you think !!!

Yeah this is a classic case of not doing the proper research before buying.... Just because you saw some other heads/cam/intake car put down a number doesn't mean that ANY heads/cam/intake combo will put down the same or even similar numbers.... And it seems you are keeping your stock intake too. Did you look at the specs for that guys set up? It's light years more aggressive than what you bought. If you make anything past 460rwhp I'd be extremely surprised.
