I got to the track this weekend, car ran pretty good but only MPHd at 116 MPH. I thought that was weaker than it should have been. ET was 11.71.

Race weight is 4220.

Running a 4 speed and 3.54 gear with 28" drag radials, so it really wasn't strong off the line, but thought it would be producing more steam at the big end.

So far, this is where I am.

Mancini 1.6 rockers

I am running the lash @ .014 instead of .018, lots quieter.

Running at 36 degrees total, in by 2800 rpm

Car feels like it pulls strong to 7,000 rpm after it gets rolling.

Checked vacuum running through the gears, even @ 7000 rpms, the gauge does not come off zero.

AFR stays right around low 13s down the track.

Compression is 175 across the cylinders.

Did I make a bad choice on the cam? The people I checked with before building gave it a thumbs up.

Wallace calculator says a little better than 500hp,what should I try to make more power at this point.

Although I don't have any dyno simulator, I was thinking closer to 600 hp than 500.
