he wants low end power
Which Cam will give me the best...
Although I feel that a cam in the low to mid 230s on a 110-111LSA will give the most area under the curve (3000-6500rpm) for a heads/cam combination, they are somewhat lacking in the 2000-2500 rpm range. To get a cam that's better than stock in the 2000-2500 rpm range, you need to increase dynamic compression over stock and limit overlap compared to a more conventional "area under the curve" cam. Doing this means that what you gain down low will also somewhat limit you up high. Compromises. But there is hope...
Something like a 218/222 .605/.581 114LSA +4 would work very well with ported heads or with stock heads provided the vehicle had excellent exhaust. You only get 41.5 degrees of overlap at .006" which is outstanding, but the high lift and fast ramps of the intake would still allow you to make strong power to 6000 rpm. Not a bad compromise at all.

Id rather have more umph down low but still have it pull nice through the band up to 6300 rpm, (rev limiter will be @ 6400)
That cam will spec as a 224.x/224.x and low to midrange trq will be in stroker territory. Also you can shift at 6300 having harnessed a nice band.
cam has only 4* overlap so easy to tune.
I've seen a XE lobed one making 400/400 and a XE-R making 412/414, this one might even top that (definately under the curve)

Thanks for all the replys guys, I am going to choose between the two - tsp 228R or tqr v.2, can someone give me a dyno graph of these with the stg 2.5 5.3l heads?

Definately not the TV2, I have that cam and the name is missleading.

To the original poster, I settled on Texas Speed's 224R with their Stage 2.5 5.3 liter heads in my 99 FRC Vette. Everything is in (long tubes, cats, underdrive, LS6 intake, Vararam), and I have a tune scheduled for the 23rd. I'd be more than happy to share my dyno graph with you after that date. From what I read in my research on this forum, the 224R should give a little better low end grunt, while sacrificing a few horses up top. I was really wanting something with some nice low-end, so I went with it as opposed to something bigger. That, and I didn't want too much lope (the 228R has 4 degrees more overlap, and thus more lope). There are other members on the board with the 224R cam-only, and one or two with heads. Check around... Good luck!
hey, LS1C5Vette,
what cc are you getting those heads in, and valve size?
i am looking at getting those heads.
there are some people running the 228r already. do a search on it, and also go to ls1gto.com, i know a couple of people have posted their experiences with it.
also, FTI as a cam with slightly higher lift, 224*-228*-111*-.600"-.600" Rebel TQ.
or 220*-224*-111*-.597"-.592" StreetSweeper-TQ
anyhow, hope that helps. and let me know.
thanks.

Ok, now I have changed my mind AGAIN, I like what I see about the 228R but I dont think ill be happy with that, I am leaning more toward the Tqr V.2 OR mabye even the 233/239 cam. Whick one of these will give me better 1/4 mile times and faster 30-150mph times??? Is the 233/239 even a streeetable cam? I know the V.2 is. P.S. this is NOT a DD car, but I dont want it to turn out like a dragster...
