What kind of dyno was it? A Mustang dyno will give significantly lower #s that a DynoJet.

If it's a Mustang, I'll say 310-320 RWHP.
On a Dyno Jet, I'll say 380-400 RWHP.

The difference?  Dyno jet is for your ego, mustang is for real numbers :bigsmile:
I'll say 348 rwhp
         390 rwtq

I just took this quote from this page were the article came from...but thanks......sounds like too many varibles to get ur panties in an uproar.....I guess a base line is a base line....do your improvements and go from there
     

A little side note, not all dynojet are the same and there are newer models of the Dynojet that can load the car the same way a Mustang can. Check out their website.

Go run it at the track, that will give you "real world numbers". My 240rwhp 318 was hardly expected to break into 14s, let alone mid 13s with a rookie screwing with the carb and too big of tire on the back  :dunno:

Dyno numbers are just another 'tool' to play with. You can have 500hp, crap converter, mis-matched cam to the rest of the car and it fall on its face. Combination as a whole driveline is what tells you "it's fast" or not.  :2thumbs:

Running at the track is still a gamble since there are variables and such with that as well. But it gives you something to compare with. I got sick of chasing .1/seconds, I got the figure I wanted and leave it as is. I have about 70 slips from my passes, from 15.0 (clean run/no issues) to 13.6.

They're all just numbers, just go beat on it and enjoy!  :burnout:

I pulled 420 rwhp with my 6.1 hemi in my challenger with only a cam swap, :bigsmile: For what it's worth...

I'm like you at least it's a. Starting point I was hoping for 500 so I need to ad another 100 hp

Are u trying to make me feel worse dude or what  :crying:.....i wish a head swap would be as easy a cam swap....but ill have to probably change the cam and intake and roller rockers to switch over to a good alum head, like an indy or some else...thats what i dont wanna do......that will be a small fortune
