Is it possible to get 300RWHP on stock heads?

With long tubes, catted x pipe and cat back, I've heard of 5.0L dynoing at 250rwhp with just those parts.
I'm think an NOS N2O kit set for a 75shot should bump me to 300rwhp.

Any thoughts?
What else do I need besides NOS's kit to run the kit on a stock Stang?

as far as i know you can get over 350 with stock heads. the 75 shot should get you over 300 if not fairly close

With the right cam, I would venture to say closer to 400 HP, if not more. I know a lot of people will disagree, but I am willing to bet more than one person will back me... To include THUMPER460.

You should upgrade your spark,and retard your timing with the bottle.

Heh....do I need to raise my fuel pressure with a 75shot?
What about a bigger pump and injectors?

I've been told, and the different brands say that no other upgrades are needed with a 75 shot. I don't know though, I would at least have a MSD ignition with the retards and a better fuel pump because running out of fuel before nitrous even with a small shot sucks.

I'm looking at the MSD 6A Ignition and some MSD coils. Should be good, right?
190lph pump should be good right? Stock injectors are fine also?
