That's right; no vacuum pump. Nothing fancy. It will be interesting to see the difference in the Dominator on gas and the 4150 series alky carb. I had a hard time finding a dyno that would do this motor. Some "reasons" various shops gave me: 1) We only dyno engines we built 2) We don't have the stuff to do a Big Block Mopar (one had 6-bolt but not 8-bolt crank connector) 3) We dont' run alcohol in our dyno flow meters.
