Default Stock Dyno numbers?

I know i must sound retarded for asking this, but i have 98 formula with custom 3" catback and vortex intake. What kind of rwhp should i assume i make? I am going to dyno after i get my qtp headers in this weekend, but i have always wanted to know how much rwhp i should be making now? Thanks

With your current mods, you will most likely be between 290-300rwhp.

I'd say between 300 rwhp and 315 rwhp. Hopefully you make even more. Let us know how it goes.

You wouldn't make any more power past 5500 with a "stock" cam. It flatlines around 5500 and then slowly tapers off a few hundred rpms later.
