H/C looking for 500rwhp
Are there any Head/CAM/Intake combinations to get 500rwhp?
I currently have a RapTR Cam, FAST 92 un-ported, Ported LS2 throttle body, Halltech Stinger CAI, 25% under drive pulley.
Heads are stock LS6 un-ported.
I have dyno'd 441-467 depending on the dyno.
Thanks

What are you looking for in your car that you want 500rwhp? Is it just a number that you want to see or are you trying to run a number?
put a 50 shot on it and call it a day...trying to get your car to 500 n/a will get expensive

Yep, been there done that 
big dollars & attention to detail is all that is required.
I also did it with a small cam 228/228, what made that build work was the ability to carry on past the peak torque. If I remember the peak torque was around 435, that's a reasonable number for a 346. When you see torque numbers beyond that my little red flags begin to fly
Heads & Intakes are better today than when I did mine a few years ago so that would be a little less money. The valve train still needs the detail, EWP, 3" exahust....it can be done

It's just a goal really. I have a 250 shot on the car so if I was after a big number I can get 700+ if I really cared about the paper.

Sarge,
Get the fast intake ported by someone who really knows what they're doing, a set of AFR or TFS heads that have been massaged and milled to get the compression up to 11.5 or so will definitely get the numbers up some, but getting 500+ out of an LS6 N/A can get pretty expensive.
250 shot on a stock bottom end LS6 is alot,,,,,you are a brave man!

I can't mill the heads because my PTV is about .050 as it is. I'd have to flycut and I'd rather not with my nitrous shot where it is. I may get the intake ported and maybe get my 243s ported. There is a guy kinda local that can get 243s to outflow AFR-215 .600 and above where my lift is.
That's probably all I can get out of it without raising the compression.
Maybe I should just start a forged lq4-lq9 build and be done with it...

If you ever decide to go with a 383 stroker I have a source for them that will beat anyone's price using top quality components and one of the best machine shops around for blueprinting/assembly, etc.
As far as head work, porting, manifold and TB porting, Pit and I will hook you up with Pete from V-max,,,IMHO none better anywhere!

I have posted this several times....but here it is again......
Stock short block/ flycut pistons/ TEA 243's (this is the whole magic to the combo)/ stock valves with quality springs and Ti retainers/ stock rockers with trunnion upgrade/ quality pushrods/ Fast 102 (ported)/ 102 TB/ Geoff custom grind (EPS)/ and all the typical bolt ons.
Here is another example of 500rwhp done the smart way.....btw...it made 495/433 with a stock bottom end 346.
http://ls1tech.com/forums/dynamomete...m-numbers.html
Mine is very similar.....stock short block/ flycut .080"/ Manton 3/8ths taperd pushrods/ stock 243 valves (super light) PRC .675's with Ti retainers/ TEA stage 2 243's (58cc, 327cfm @ .600)/ stock rockers with Comp trunnion upgrade/ stock lifters/ EPS custom cam in the 23x/24x @ 107 range/ .040" 3.90" mls head gasket/ Fast 102( ported by Mamo and matched by TEA)/ NW 102 TB/LS3 injectors and rail/ BBC EWP/ TSP longtubes and x-pipe/ Dynomax bullets/ UDP and everything else is stock. And btw...Im scr of 11.6 and dcr of 8.7
So recap....stock long block with cnced stock casting heads with quality valve train and a great matched cam. Just very attention to detail oriented build...but yes 500rwhp is acheivable. Without breaking the bank !!!!!!

I had this beast on the dyno and we were seeing upper 490's when the clutch started to go. It will be back on the dyno before x-mas. But now it has 4.10's and a RSP BC2. O..and a Nitrous Outlet dp moneymaker in the 102 !!!!!

Good stuff. How does that 107LSA drive? Intake and heads port matched?
