yeah trust me I've read just about every L92 thread there is to read and most if not all are on 402/408 setups...very few on the stock 6.0 bottom end.
but I got cam specs from Pat G should be pretty good I'll have the cam in my hands in 3 weeks or so...

There's also the thread in the dyno section awhile back that had a GTO, stock bottom end, L92's and Virginia Speed's own L92 grind that made 508 rwhp thru a 6 spd w/ l76 intake. The heads were ported L92's from WCCH.

In the other thread there is a member with the screen name 8bygoat and he has a stock bottom end with L92's and his cam goes against all conventional wisdom of an L92 headed motor. His specs are 232/236 600/600 113lsa. In his sig he states that his 05 gto makes 452 rwhp thru an auto and runs 11.22 on the motor. The cam was supposedly spec'ed by Ed Curtis.

The "conventional" wisdom in many of these L92 threads isn't wisdom.
Ed knows what works....I've put a 230/234 in a LS3 car very similar to that cam and works very, very well.

not knocking you just seeing exactly what it did, or track times.
87silverbullet I did see his results...damn good I hope to be around there if not a bit better.
didn't see the GTO but Shawn told me about making those numbers damn impressive.
my cam I guess is considered "conventional L92 wisdom" it is ground on the LSL lobes 227/235 .614/.621 113+4.
here is another cam Patrick suggested it made 460/446 on a stock bottom end ls2 w/ STOCK L92 heads.

Looks like a good cam. I am choosing to go with a cam from Geoff at EPS that is just barely bigger than yours it measures 230/246 600/607 113. He is going to be tuning my car and it is a cam that he picked for my car. I hope to put up numbers in the ballpark of all the threads we mentioned. I really want to put down the track numbers everybody are making.
is that cam going in a stroker or a 364?
