I think I got fantastic results with my little cam. 601/588, but the air temp was only 50 degrees so about 580ish is what I'm saying I have on the street with 10Lbs of boost. My cam is a 221/226, .567, .564, on a 114LSA, and -4 overlap. This cam works great N/A or boosted, functions with a 2100 converter or higher and operates from 2000-6400. If you wanna get really rowdy Pat will spec you out a MF for the L92 heads. E.P.S will most likely grind it and Geoff is a really really nice guy that will work with you. I never liked off the shelve Comp grinds. I always ran Lunati, Cam Motion or Iskendarian before I found out about Pat. So there are some better choices in my opinion. Specially for a race car.
Sounds cool

Exactly what bozzhawg said. With that lift I build 10 Lbs of boost, Don't float valves and all I had to do was change to Nitrided .600 springs, and didn't require harder pushrods for the RPM I turn. Note: I did make that horsepower with some tweaked LS3 heads and hollow valves, so it's not ALL cam.

A local shop tried a 266/261 and that engine miserably failed with 390ish at 4400. Sounded radical though.

There's history in the LSx platform to justify trying it. LS1's respond nicely to reverse splits for street use. I'll bet the LS2 with its crappy stock intake would do ok with a reverse split. too. It's a great way to build a lot of midrange torque while keeping overlap down (i.e. better drivability). The trade off is power will drop off a little faster past peak.
