How much HP do I really have?

[vetteeatr]

Just wondering if that may be a little low since stock is 225

Heads ported and polished should bump it up a good 40 horses alone, I would think.

My exhuast should be worth another 20 HP I would imagine.

I also have a k&N filter and underdrive.

Dont you think, maybe, with all the other stuff that's supposed to gain maybe a few horses each thing I would be close to 300?

Around 340-350 with an intake and throttle-body and maybe 380 with a good cam?

Am I unrealistic?


It's just that I see in magazines 350 horses for the Holley Systemax and my heads will flow more and I hear the cam is not that great.
Not to mention my slightly higher compression and a few other things.

Am i just fooling myself?

Why does my combo not perfrom around the Holley Systemax?
