Re: horsepower est. and 1/4 mile times with boltons My guess would be that you are somewhere between 315-325 rwhp. Track times......? Ya never know. It's an M6, so it depends on your driving more than anything.
Get some headers and nitrous.

Re: horsepower est. and 1/4 mile times with boltons I have a 03 sierra with the 5.3 BUT I thought I would make some suggestions anyway. 
I would definitely go with some headers. Im getting some AS&M's and they look to be some of the nicest headers out there. Pretty much he only option for my truck, IF I want long tube headers.
What long tube header options does your car have?
Headers would REALLY open up your engine.
Another mod you may want to consider is the LS6 cam, springs and maybe pushrods. I would LOVE to put them in my truck but since its an 03 I want to hang on to the warranty for as long as I can.
I have seen recent dyno charts showing a gain of 40hp to the wheels for a basically stock 5.3L LS6 cam equipped truck.
I also recently got the predator tuner. So how do you like yours? Did you do a before and after dyno with the predator?
I would really like to see the dyno results on your car AFTER the custom predator tune!
Anyway good luck and hope I gave you some constructive suggestions.

Re: horsepower est. and 1/4 mile times with boltons I have heard the same thing for LS1 based engines like my 5.3. LS6 intake manifolds are not really worth it at least definitely not for a truck BUT the cam, springs, and pushrods ARE!
