Engine Dyno Questions!

Maybe "I assumed" Is this out of the car or in the car for the dyno?

You need SOMETHING for electronics which is why I posted the GM HEI as an alternative. If you or the dyno shop has an MSD you could us that as well What does HE have for electronics
The engine is out of the car. No alternator, thermostat, fan, etc. It has the fan and crank pulley only. Fuel pump block off plate installed. Will be running with stock exhaust manifolds, restored original thermoquad carb that was tuned for my engine specs. Stock distributor restored and tuned to my engine specs. Stock reproduction coil.
