is 500 unrealistic on a 346 for a DD? right now i'm running a forged 346, MS4-110-LSA, Patriot LS6 STG 2.5 milled, 36lbz, 255 fuelpump, 12:1, M6, hooker LT's 1-7/8, TSP true duals, 12-bolt. is it unrealistic to change to a better flowing head and a bigger camshaft to achieve 500?

With your set up now i would put your hp around 470-480. The only people i have seen break 500RWHP on 346 are guys using the TFS 215 heads and AFR 205. If i was going to do it i would go with a vengeance ported FAST 92 with a Rev extreme 105mm TB, Patrick G custom cam, TFS 215 heads milled to 59cc. I have seen a similar combo make 511RWHP and 430RWTQhttps://ls1tech.com/forums/dynamometer-results-comparisons/938008-511-rwhp-430-rwtq-346-wow.html
02 Flame Red Trans Am ported heads, ,Cai, Real Ra,16 Point Subframe Connectors, ls6 cam,lots of stiffness welding Wanting too someday become a Nhra Dragster/Nascar driver someday .. seeking Sponsorship any info needed i have track times and 08 911 Turbo's in the dust
best track time 12.29
11's here i come when a Safe n Sane tune when n20 install is done
wow
the best ive seen heads/cam cars do, REALISTICALLY and at the cost of driveability sometimes is around 420-450rwhp in a properly setup 6-speed LS1car. But it takes something EXTREMELY radical to make more. But honestly to make 600hp N/A on motor, just get yourelf a flux capacitor >>>check our sponsors, they sell 'em

540RWHP????? that is way to optimistic. Dunno how you came up with that number With your set up now i would put your hp around 470-480. The only people i have seen break 500RWHP on 346 are guys using the TFS 215 heads and AFR 205. If i was going to do it i would go with a vengeance ported FAST 92 with a Rev extreme 105mm TB, Patrick G custom cam, TFS 215 heads milled to 59cc.

guys, check out patrick G's combination that got him 500rwhp+, it seemed pretty streetable to me...you absolutely CAN get 500rwhp streetable, it just takes a lot more thought and effort than most people here are willing to put into it 
Is it possible? Yes.
Can it be daily drivable? Yes.
Can you do it with just a cam and head change? Probably not. The list of supporting mods is long and distinguished.
Will it be expensive? Yes. 480rwhp can be achieved without breaking the bank, but the last 20 rwhp get pretty expensive.

I guess my 507.9RWHP with CARTEK LS6 heads does not count?
Or the fact that I am running a Fast 90/90?
Or the fact that I drive the car all the time, not a daily driver any more since I have a beater, but driven enough on the weekends, and driven to and from the track every time.
What about the fact that out of the many 500hp+ H/C cars I am one of only 2 or 3 who har run the times at the track to back up that HP?
Really???

10.3@132+ in a heads and cam car that's also driven to and from the tracks, very impressive.

supposedly the TFS 215's are the shizit for 346's. Thats probably what im going to get after i have the money and then spend every second of my existance looking at dyno graphs and researching every flow number known to man.
500hp to the motor is realistic. To the wheels, no. You need every mod possible and must be done in perfect harmony to get 500rwhp.
I'm at around 420rwhp with LS6 stage 3 heads,LS6 intake, 1 3/4 and ORY, tune, nice cam. Now I'm hoping for 450rwhp with a ported FAST 92mm. The last 50 rwhp would be too much $$$.
Then I'll keep my money for a LQ9 408ci swap instead of EWP, new exhaust, new heads and tune..
