got a 94 Trans am for 3 years now, auto 4l60 2.73 rear axle, never dynoed it
im loocking for some extra power without boosting it
engine internals are completely stock, long tube headers, y pipe, flowmaster muffler, cat delete (no regulations in my country), egr delete, msd coil and module, 58mm tb

what kind of cam and other internals do you guys recommend for a 300-400whp daily build
thanks

58mm on a stock automatic
CAI like K&N or if you have a ws6 hood in mind do the Ls1 lid set up it works very well
You need some gear in that car, 3.73s come to mind however, if you find a 3.42 rear from a 6spd car that will work
New valve springs, 1.6 rockers
Underdrive crank pulley
3200-3600 stall with the largest capacity tranny cooler you can find to fit
160° thermostat
And most of all have that pcm tuned....
I personally like the cc503 cam and heads done by someone reputable cough cough LE2s or AI you will not be let down by either..

Stall & gears next

3.23 is okay but I would run a 3.73 like 96lt1m6 had in mind
cc503 is a great cam but if you decide to go with AI or LE (advanced induction/Lloyd Elliot portworks) I would discuss your goals with them and have them do a custom grind
You'll want to have the intake done when you do the heads if you haven't already 58mm TB on stock intake is not good

3.23 gears and an Lt1 are not a very powerful combo. Ls1 can do magic with 3.23s..... Lt1s need a little more gear to put us in that sweet spot.

What benefits would give me a 3200-3600 stall? (dont know much about them)
The problem with that is that i live outside the us so i need to order my cam and others and have them installed here
Got my intake done to go along with the tb
Thanks

Acceleration, gets the car moving and keeps the motor in a usable powerband. I have done the swap from 2.73 to 3.23 to 3.42 to 3.73 and 4.10.... the first 2 don't have a considerable amount of difference from my observation. For an automatic 3.42 and 3.73 are great but the 3.73 gear is what i would consider optimum.

The transmisión will still change trough gears normally?

AI and LE are not the only players in the game. You can talk to Craig from GTP as well:

CAI, 3.73's, a 3000+ stall, and a tune will make a huge difference. Nitrous is also a cheap way to add 100-150 horsepower on demand. The stock LT1 can handle a 150 shot of nitrous all day as long as it's set up right.

can you please explain to me what the benefits would be from a 3000+ stall converter
dont know much about it
thanks
instead of your current converter which is around 1600-1800rpm the car will leave at a higher rpm more into the power band of your engine. They do generate more heat so you will want to upgrade to larger external transmission cooler.

in simplest terms a stall converter will act like having a manual with the ability to select the rpm your car will launch at based on the advertised flash rpm.
instead of your current converter which is around 1600-1800rpm the car will leave at a higher rpm more into the power band of your engine. They do generate more heat so you will want to upgrade to larger external transmission cooler.

so with the mods that i already have + bbk underdrive pulley, CAI, 3000+ stall and tune.. how much whp do you think the car would have? just to have an idea
thanks

Stall & gears don't add horsepower in fact I believe they reduce it if purely looking at dyno numbers but they wake the car up quite a bit.
And since you want to know more about stall converters this write up should help you understand a bit better http://www.badasscars.com/index.cfm/...d=78/prd78.htm
