Question how much hp!

just wanted to know how much HP, I would get out of some headers and a ypipe and a spintech exhaust or Lm. im thinking either pacesetters or slp with matching ypipe. I made 350 rwhp and 348rwtq stock! just wanted to know because i dont want to waste my money if i don't make any more hp!

No, you didnt. Thats impossible, I have to raise the flag . If you were totally stock, that is flat out impossible.

and yeah...your question... headers -Long tube headers and a Off road y usually yield an average of 15-25 RWHP depending on tuning or no tuning and the type of headers and Y pipe used.

all the haters seem to know a tad about the ls1 engine(not saying that you dont know a thing) and all the haters have never heard of such 100% stock RWHP numbers... if its true well... awesome man! you got a hell of a car.
12.72@110 is very strong VERY strong for a stock car. i dont mean to call BS on you.. but what was your 60ft? what tires were you on? what were the weather conditions?

You might just have one of the most powerful/fastest stock LS1's ever. Even with those mods, 350 rwhp is a tad high for me to believe.
