asa cam question I tried to find my answers through search but didnt find everything
So my car is a 01 z28
Auto
2.73s
stock stall.
mods are
jba shorties, stock cats, slp y pipe, slp loudmouth, whisper lid, ported maf, ported stock throttle body, smooth bellows, dyno tuned by a local guy.
so im thinking of changing the route of the car temporally... i was planning on spraying it. and i still want to in the future. but i want more power all the time for now. so i saw some good things of the gm asa cam.
basically my questions are
1. How will the cam do with the stock stall and gears, or are a stall and gears required for this cam?
2. Will the cam work with the tune i currently have untill i get it back to him for a re tune?
3. I heard you have no need to upgrade valve train components with this cam, Is this true?
4. In the future will it be a good cam for spraying it.
Thanks for the feed back

1. Not good. The 2.73's will really hurt. It's possible to run it with the stock converter, but coming from a guy that actually did it for a year.....you don't wanna do it. You'll want at least a 3000rpm stall speed. For gears, I ran it with 3.23's and it was ok....3.73 would have been better.
2. You'll need a re-tune. The VE will change dramatically with the ASA and will need tuned accordingly to achieve a safe WOT afr.
3. You need LS6 valvesprings at a minimum. Stock rockers, pushrods, locks & retainers can be used, but hardened pushrods are a good idea.
4. You betcha.....I plan to throw a 150 wet shot at mine eventually.

Yeah, this cam will definately need a tune.
jmm98LS1 is right, 2.73's and stock stall w/ that cam will not be fun.
You'll also have to run to the LS6 springs. I upgraded to the LS6 springs, hardened pushrods (7.425), and LS2 chain, but kept the stock rockers and retainers. I'm also planning to throw some n2o at it eventually!

Might as well get a good set of springs and get a cam similar to mine if you want ASA like torque and lope. 226° .571"/230° .575" 109° LSA +0°. Or even XE-R 226°/230° lobes. The XE-R lobes will idle better than the ASA or my XE lobes since they have less duration and overlap at .006". You might also want to see about getting long tube headers in the mean time. Tune, converter are a must. Gears should be considered.
