from what i've read the L92 head likes a big split as well as the carb style intakes liking the intake valve opening 4* or so sooner. as it sits i'd guess your setup to pull ~420whp on a dyno. just remember, dyno numbers don't mean ****, ESPECIALLY when autotragic cars are generating them.
good luck and looks like a nice setup. i will do an lsx bu, when is the question haha.

I'm sure he doesn't want to **** around if he doesn't have to. Time is money and I am guessing he isn't made of money. Just contact lg motorsports or ed curtis or speed inc or some other very reputable shop with lots of l92 experience and have them grind you a cam a be on the road. That cam he has in mind will not work good with l92 heads I know just from reading all the l92 posts.

Here is what I am running. Comp Cams custom grind - 222/238 .581/.605 114+4. This only give 2 degrees of overlap at .050. Idles very good, little lope, no surging.
The other mods are in my sig. The DCR came in at 8.5 and SCR is 10.8.
If you were doing a EFI setup I would give you my tune for a base to start with, that was the time consuming part, coming up with a tune when you start with nothing.
I have not had it to the track or dyno yet but it feels very strong. From a standing stop in drive it spins through 3rd gear. From a 20 mph roll, it lights them up with ease. I have your basic street tires (P255/60r15) so DR's are the next purchase.
