Road race ls1 cam I posted over in the road race section but didn't get too much. I have a bone stock '02 LS1 with open intake (cone K&N on the MAF) and 1 3/4 shorties with dual 2.5" w/ x-pipe & straight through Magnaflows. It's in a relatively light weight 2600 lb wet w/ me road racer. I'm looking for more power and think a cam is the way to go. I want to be stock reliable and relatively low cost cam/spring only change. I'm thinking the ASA cam is the way to go with the low lift but are getting mixed reviews and the huge overlap and possible tuning issues scares me. I've read many many threads here on this topic but see more varying views than anything and not much specific to road racing. Any other recommendations?
Thanks
Cameron

I've been running my TR224 on road courses and street use since 2004. Lime Rock Park, Pocono, Memphis, and Indy Motorsports Park...drove the car from NJ to each of these and back home.
Got 28mpg on the interstate drive back from Memphis last year, loaded down with tools and slicks.
I'd only run dual valve springs, no single beehives for me. Back in 2004 when the engine went together, I bought a set of Crane springs and had them rate-checked by the shop...two were out of spec and were replaced. Checks were done at installed height, and again at max lift. This is a cost-effective way of quality checking valvesprings and I highly recommend it.

.595 .585 with 110+4 LSA
