Re: got the stroker dyno'ed...results inside
Air fuel ratio starts off over 15 at 2k rpms (maybe my part throttle stumble between 2000-2500)?, sharply goes down to 12.5 at 2500 and flatlines out at 12 to 12.2 through the entire RPM range. It does kind of fluctuate a little where the cam drops off at 6300. The redline on the chart is at 13:1.
As far as the "brown" smoke.... did it do this on all the pulls? How long has it been since the car has been run hard? A buddy of mine had his car off the road for a while for some mods, and the first pass at the track, it blew a 30-ft cloud of orange/brown rust out the back of the exhaust:

To see the charts, click the link in my sig, page 5.
The cloud was worst of the first pull, not so bad on the second. But it's all been apart recently and the motor has less the 5k miles on it.

The heads will allow the HP #'s to climb until 6000 RPM on a 383. The car will PULL higher but the HP #'s will be done by 6000 RPM on a 383 with a hyd roller. If the #'s are peaking before this, tuning might possibly get the #'s to continue to climb.
If you look at some dyno charts for 383's with my LT1 heads, you will see all of them peak at 6000 RPM or so with a hyd roller unless the cam specs or tuning is the hold up.
