70 Duster/5.7 hemi finally makes it to the track...

You can run the hemi's a little on the fat side (12.2-12.4) and they do very well. A little on the lean side and they dont like it so much.

Have to agree with this - my last dyno session was a peak hp run...no tuning - the AF was low 13s

When I got to the track I found 1.5 stages richer yielded better results in mph.

Now I have the AF around 12.4 , the intake plenum divided and more initial timing Im hoping it'll show even more at the track...
