with out spray. what can i do for the most horse

i have exhaust. but i want more power

What do you have for exhaust? Headers too? Pretty much anything you do that adds 50-60 more hp. you better plan on a new tranny soon. You can go with a street/strip TCM. I did this and a few thousand miles later it started slipping about 5,300. I wasn't hard on it either. There are deff. things you can do to prolong the life of the trans. such as another tranny cooler, and corvette servos.

I would leave the heads alone unless you are planning a cam. In that case you would need a stall and start looking at a stronger tranny for sure. Do you have headers or no, that is the way I would go along with a tune. That and get a tranny cooler also like what was said above. You can always save a bit more and get a maggie But then a stall and tranny are needed. These trucks need some better transmissions when you go after more power. At least the rear can take some abuse unlike f bodies lol. Actually I would use the money to put a RPM Stage 5 4L70 in it along with possibly a decent stall. Then atleast that would be out of the way...

For $2500 you are going to be best served by getting a converter (3200-3600) , LT headers (Kooks or ARH) and a CAI + Tuning. That will be just slightly over $2500

Another thing to consider. Are you doing this yourself or paying someone else to do it? Also, do you need to buy new parts or can you accept buying used. Check out tbssowners.com

The exhaust did nothing for your power. I suggest tuning it and efans. Lot cheaper than 2500 and itll give you a nice feelin. But be aware, you better save up for a trans, cause its gonna go...

If you want more, stall it... I'd only cam it if you don't give a damn about MPG.

didnt see that it was an SS

you get a stall your trans will let go. i had a yank ss3600 and my trans lasted 4000 miles. but a stall will give you 5 tenths gain in the 1/4
