Hell, I did just the 1.6 full rollers on a stock cam and picked up about 20/20, with a tune.

You'll see benefits, but not as much as you might with heads/cam.

you will be some where between, 320 and 360 at the wheels, however, be careful with the cam choice as in, do u want to keep it when head work is due, do u mind High idle, what other mods are going to have with the cam only setup?

remember, big is not always better.

good luck,
Eyad.

so far i have pacesetter headers/ory and borla with an slp ls1 lid on my lt1 w/k&n filter, i was thinking about a 232/230 or so, maybe up to a 236/233. If i get one now i can do heads later on right? I am pretty much just wanting to do the cam tho because when my lt1 blows im eithor going to put a 408 stroker longblock or a 6.0 LS2 engine in it, but id like to see some gains without spending 1k on heads

you absolutely need all of the supporting mods as well, they are listed in a sticky, like headers back and at least an intake

A cam with a little more exhaust duration might work a little better.

the 113 LSA is to tame the cam, and flatten the curve out. not the best idea if you ask me. you could make alot more power with a slightly less duration(224), on a 110-112 LSA. wow, I have never seen a site with so many over caming people.

i agree with getting it on a lower lsa. id go with a 230/236 110lsa.

i have to disagree with the lower duration for more power though, look at other peoples dynos. ive never seen a 224/230 make more then a 230/236. maybee if your talking in the lower rpms, yeah it would but who wants low rpm power anyways

And that is why they grind the cams advanced 4 degrees from the factory.
