Whose making 550rwhp N/A on a 402 LS2 stroker If yes, what compression, heads and cam specs you running and any 1/4 mile ets and mph? I believe this is going to be my next set-up and my goals are a reliable, bullet proof N/A LS2 402, that will run 10.5s at the track at over 130 mph in my C5 Z06, and the next weekend can be flogged all afternoon at a road race track!!

these are pretty similar to my goals. I should have my motor done by summer. I plan on going with TFS 225's and a pretty radical cam. My current package is really tame since it was my daily driver, but since I only drive it once or twice a week now I plan on going big and nasty. Also, it will be setup for a big shot of the squeeze down the road once I get the rest of the car ready for it

I found a tuner who has has built one at 12:1 to 1 compression (9.1 to 1 dynamic compression), TFLow 225s, and running a BABY cam 236/240 cam, who is running N/A 10.3s in his 3400 lb F-Body, at 136, through a MANUAL TRANNY, and 4.57 gears and making 551rwhp and 495rwtq through a 9 inch rear end, big slicks, SAE correct on a dyno jet and i have seen his video and time slips that back up the dyno numbers. I don't know, but seems as if a few are doing it (and he tested 6 different cams) some much larger and the baby cam is making the most power. This is running on 100 unleaded at the track though and that certainly does make a difference and the higher compression seems to be the difference here along with the best heads on the market the TFS 225 (out of the box)!
Also has a fast 90 which is ported and good for 15rwhp according to his dyno tests. Some motors just have the right COMBO and make HUGE POWER and this seems like one of them.

Streetable is a relative term. With an auto and big stall, you can make almost any big cam "streetable". The M6 is not so forgiving and is much more difficult to smooth out bucking/surging that comes with big overlap in low rpm cruising required for "street" manners.
550 is just a dyno number, thats worthless to chase. We have put togeteher a few combos that would easily do what your looking for in track times though, have some heavy *** auto cars that trapped that number.

Already have the motor built and ready to buy and it runs consistent 10.3s at 134 to 136 mph (all motor) on a 3400 lb race weight Z28, with a MAUAL TRANNY. Big stalled auto would run into the 9s with that type of power this is making. Has less than 100 miles on a brand new motor and 20 dragstrip passes (no spray/N/A). The track is what matter and we know this and this particular 12:1 to 1 compression 225 Trick Flowed Headed LS2 402 is certainly hauling the mail and should propel my Z06 into mid 10s all day and that's what i'm looking for!
Was just wondering who else is having these type of result on a max effort 402!

I have E-mailed this company and asked them if this engine is streetable and they tell me a definate "yes". I want a totally streetable engine, I just have to determine if their defination of streetable is the same as mine. JB http://www.w2wpowertrain.com/pc-78-8...l-402-ls2.aspx

My 408 with ET 4245`s and a 250 255 640 640 112 drives like a baby now. got a SD tune and it did wonders for driving around town. 530rwhp and limited on shift point to save tranny right now. I paid more for the Speed density tune but it is so much fun to drive now. Me and the wife and kids just got back from popping the T-tops off and taking a sunday drive. My car weighs 3600 without me. I`m 220lb so I will be curious to see what I run now. When I just had H/C and 100 shot I got 6.9`s- 98.2mph in the 1/8th. So I`m hoping mid 10`s on motor(408) and I don`t know with my 200 shot for a pure street car, A/C and full interior!
