Can I Hit 500hp?
Mods Are As Follows Cam, Lg Long Tubes, Fast Intake, 90mm Throttle, Underdrive Pulley, Vararam Intake. With These Upgrades I Pushed Out 453rwhp And 421trq. Next Week I Will Be Adding A Set Of Afr 205 Heads. So Do YOU Guy's Think It's Possible To Hit The 500 Mark.

nope.
and im also going to have to raise the BS flag if you think you are making 453rwhp on stock heads with only a 228 cam. 421tq?? i doubt it.

Go with the TFS 215cc heads.
Have the fast port-matched to them.
You have a good chance of picking up 50rwhp with those 2 mods.
If not, you can try to squeeze every last bit out of it by doing minor mods like a better water pump, etc.
500 rwhp is attainable with that cam, you will definately at least get close. Don't get too fixated on a magic number.
I would not change the cam. That is a good cam, and any bigger might be over-camming the motor, and killing low end grunt/throttle response. I personally think cams bigger than yours in a stock displacement ls1 or ls6 only make since in a stalled-auto application. But I am certainly no expert, just a keyboard-jockey.

Like I said though, don't get fixated with the pretty, round number of 500. You can get close, and close to 500rwhp through an m12 tranny and 3.42 gears will be awesome.

I just made 500RWHP with a 234-240 112 cam. Of course that was on a fully built forged 402 with CNC'd L92 heads.
My fully built 346 with CNC'd stage 2.5R heads, 230-236 112 cam, ported FAST 90/90, LT's, etc, etc, etc made 460.
Phils C5 Vette (forum member) just dynoed 425/400 with a 228-228 114 cam, AFR's, LT's, ls6 intake, etc.
MCLEOD (forum member) just made about the same with the same setup.
KIDCID (forum member) 224-228 made a little more RWT than them and about the same RWHP through an automatic with the same setup.
These were all dynoed in the last month during a Dyno Day in our area.
453/421 - I doubt it but good luck!

Last time I checked... a 228 cam is a SMALL cam in an 346cu LSx... LS6 243 heads still suck for flow, not much better than an LS1 241 casting head.
I agree with C5KIDD amd WKMCD BS flag is raised..
Post a graph... but if you've ever played with/seen the dynojet software up close... you can make it look however you want...

I noticed that you are sporting a well heeled "04" it DOES matter the question would have been yes you can but should you??? as before "02" it might have been quite a gamble with powdered rod and p.c.v. issues as well as others so the answer is what are the "grind" on the cam?? those heads are too small for the big 500 but find a real "Cali tuner" and you'll be close enough. AND 9 out of every ten that use the fast 90/90 have over done it on FLOW its about displacement and the 90/90 set up is a total waste on under 400 cubic inches YA YA I know but just Waite in about an other year when people start looking for more horse power someone else will say the same thing and everyone will say WOW ! Its just that right now its the latest thing and an awfull lot of tuners have bought a boatload of those things and they "must go".

IMHO It really depends on the Dyno, so many variations. SOP and MPH at top end of 1/4 mile is the real dyno. Peak numbers are over rated.
The heads alone will net a true 20 RWHP
A larger Cam will get you 15 RWHP
If you lower the Chamber CC to 11.5 to 1 Compression and use a tuning program such as HPT you will reach your goal.
You will not want to run this tune on the street.
It takes 45 seconds to change it once you are familiar with program.
Good Luck!

I am also not convinced these numbers posted, with the mods listed = the posted dyno numbers - that is if the dyno was on the up and up
Post these in the Tech Section - be prepaired with a flame suit

22X cams with heads usually put down around 400-420ish. where did the rest of his 50 rwhp come from?? basically youe saying he picked up over 100rwhp with just a small cam?? dont think so

also... for everyone saying its possible.... lets get a list of all the members we know with 500rwhp N/A with stock cubes
problem is he isnt actually at 450rwhp, so its not just going to take 50rwhp to get him there. i think with that cam and a nice set of heads, hes looking at maybe 450ish
RETROTECH.......... what numbers are you getting out of your setup?? thats a much larger setup than the 228 and LS6 heads. bet your not even at 450rwhp??
