... No effin' way!

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!

Sounds like the setup to get then! Pretty healthy setup, thats what you shoudl see out of any 408 with decent heads cam etc.Our stuff is running less compression, moderate cam in the upper 240s, and carrying around 2-300 lbs more normally than that as they are normally running NA when they are out of nitrous
, we really havent ever built a max effort NA setup, but there are lots of guys who have and have been 8.90s to 10.0s range NA depending on weight/compression. TXCamss comes to mind, nothign crazy pump gas motor Erik built, 3400 lbs and 9.8s or 9.9s and drives it around some. LS1 Tech Stories

I agree 100% as W2W is one of the premier engine builders here for sure (along with several other great selections-LME, Canadian Performance (Dave builds bad azz ****), ERIK formerly of HPE)!

I hope to hit 500RWHP through a A4.

460-470 through an M6. Youll see more of 450.

Richard at WCCH really feels that the intake is now the limiting factor on this setup. He's probably right. Someone really needs to come out with a cost effective street manifold that will keep up with the setup.
Ed and I are talking about another cam option this morning and we'll see what develops.

I'm running a 13-1 402, et 240 heads, eastside stroker grind cam,fast 90/90 and made 445 rwhp thru a th400 with a non lockup 5800 converter, with a nitrous tune. On motor it ran 10.8 spinning the rims in the tires, and the suspension is not anywhere near 100% yet
With a set of 28 et drags screwed to the rims, I'm epxpecting 10.5 from it on motor before it sees any nitrous

and i think thats gonna be best case scinario
and i think thats gonna be best case scinario
BTW, it made over 720 on the engine dyno without the nitrous and its a purpose built nitrous motor. Sick enough that no one else has made that kind of power from an LS1 and the same parts.

revolution and a half per run, 90% at the launch we figure, judging by what it did in a 1/8th mile pass. Guy that mounted the tires put WAY too much soap on them.
