Chassis-dyno time

[BigBlockMopar]

Had my Dart on the chassis-dyno again recently to find out what the engine-swap from 318 to 360ci netted me.

In short, it was 234 RWhp @ 4700rpm and about 295 ft/lbs @ 3550rpm.
About 64hp more than the previous 318 engine.

The 360ci engine also runs on LPG Propane fuel and has an A518 and an 8-3/4" rear axle behind it.
The LPG fuelsystem line and/or lockoff-valves started to act as a restriction because the AFR-readings started going leaner above 3800 rpm.

Combined video of all the runs with dyno-charts to go along (Sound is way better with headphones or good remote PC- speakerset);

Very sweet sound
Nice torque line.

Even though the runs start with the throttle pretty much at WOT and loaded against the counterforce of the dyno, the dyno-operator still had to feather very slightly into the run to prevent transmission kick-down.
At around 2600-2700 is when he felt confident to go to 'full-WOT'. Could be seen in the torque-line as it curves 'up' slightly more.
I already had loosened-up the linkage quite a bit but didn't want to drop the trans oil pressure too much in situations like these.
Runs were made in 2nd gear.
