well for you my friend your in H-town you have many great choices to choose from but if I were you and its your daily and it really depends on this...….do you care about gas mileage and can you tolerate rowdiness? just realistically up to you? I drove my WS6 for 10 years with a RPM5 cam same as MS4 with a Yank 4k stall as my DD love that car and it never failed me sure the gas mileage sucked but I enjoyed my acr and on the HWY it wasn't that bad lol

450 is about 65 hp over stock. Not sure how much more you can go without getting hard to drive, and tearing into the engine. It already lurches pretty good at slow speeds.

Not sure which cam, or who tuned it. I had the tune checked by a guy in Palestine, tx. He said the tune was right on.

lmao yea my neighbors got use to it tellimg me it was their 5am alarm clock hahahahaha ok so my suggestions would be this long tube headers xpipe and your choice of catback then either Halltech or Vararam CAI go with either BTR stage 3 or a Cam Motions titan king ls3 cam or even the new GPI cams and a Yank PAS 3800 stall or a Circle D in that same size along with a good tranny cooler and most importantly a great Tuner I believe PAT G is close to you or one of the big shops down south oh and watch out for your stock radiator bad design flaw I bought the ECP version American made and $250 not $700 like the others lol oh and for the E85 go with the DSX kit and ask your tuner which injectors to use and fuel pump if necessary to use that right there will meet your goals make you not wanting to get out of your car and kick *** on the streets and the track oh and don't forget to upgrade to some wheels and tires that power will get crazy out of hand hahahahahahaha good luck kiddo and be safe respect your car and the power it makes now and what its going to make that's the key!!!!!

Yeah, I don't want a bigger cam, idling in any gear sucks. Also trying to ease into the throttle can be jerky. I am learning to work with it, but would not want a wilder cam. If I add hp it will be either nitrous, or supercharger.

hhhmm ok first im not going to bad mouth your tuner ok but you should find out which heads and cam is in it and is your car a M6 or A6 just being honest a mild port and very mild cam could possibly be what you have and with a A6 I can see those #s as long as your happy then all is well

my tuner got my old 02 WS6 with a 4k Yank stall and a cam specs of 238/244 110 lsa 612 lift to drive smooth enough for me to daily it 10 years thru all seasons that car never surged or bucked on me the only thing it did was eat up gas while kicking *** lol I use Sam@AMP in NTX
Auto or manual? Mine does not like to be between idle and about 1200 rpm.

Hi OP my suggestion for your heads and cam build is a get a good cnc job on your heads bump compression to 11.2 get a good set of aftermarket lifters as non of the factory were made for heavy valve springs get a good Hydraulick cam prescription my suggestion 234 to 236 intake duration max highly suggest tsp cams get your intake manifold ported and radius rods install have your oem throttle body ported.
Get a set of 3.42 diff gears and a Yank pas 3400 stall converter 10.5 in 1/4 mile my LS3 went 3.5 years till a rod let go but it sure was a lot of fun, what would I change if I was to start over again? I would definitely throw in a set of forged rods my motor would still be alive.
PS. There’s some will try to talk you off the diff gears ask them they never had em.
Get you a good tuner one great on 6l80

I agree with you sir on your suggestions although man have ran in the 10s with stock gearing including Shane Hinds FAP tuning his white 08 A6 is all over youtube with stock heads even now a set of 342 gears with a smaller 3200-3400 would work great together so yea that's a good idea as well just another extra cost and as far as your car letting a rod go with a stock LS3 is more of a fluke than anything
As far as the fluke there are two others in my vicinity with same outcome within 6 weeks time and all were NA including an LT1 making 550 whp which lasted him 3.5 months will you be please explain these other two flukes.

First off respect for doing an NA build, not many people go that route. Second 500whp is fine. I'm currently at 518whp (NA) and don't have any issues what so ever. The only thing I ran into was blowing up my differential at the track, but that was my fault.
I'm currently running: CNC ported heads, Compcams 227/243 camshaft, 1.7 rockers, trunnion upgrade, Kooks Headers, Corsa Exhaust, Vararam CAI, Z06 Clutch, and a street tune.
PS I recognize that gas station are in you Baytown by any chance.

Sir I made sure to refer to the OP on my post he is the one asking how to, obviously others have their way but we don’t all have same paths so I meant to share how I did it and it worked for me instead of sharing Shane Hinds I suggest you share yours.
As far as the fluke there are two others in my vicinity with same outcome within 6 weeks time and all were NA including an LT1 making 550 whp which lasted him 3.5 months will you be please explain these other two flukes.

just did my cam swap TSP stage 3 231/246, .640/.615 111 LSA. got it locally tuned (not wideband), it drives good, no bucking if it does its because im still getting used to it. only complaint is the exahust smell in the cabin. i have speed engineering LT with xpipe (not cats) straight piped to the muffler. its loud and obnoxious lol. as far as power not sure what numbers im hitting will not get dyno tuned till probably march/april. first i need to fix the exhaust smell, even though its part of the pay to play and the smell is inevitable. its not as fun to drive with the a/c on. With these texas heats....you need a/c! All in all my goal is also 500rwhp NA. up next will be the ported stock heads from TSP and the rod mod on the intake, or i might go with an atomic intake. after that, a clutch will be necessary too. get ready OP cause its gonna get pricey! but money well spent! good luck my corvette brother!
