Ah, I missed your comment about the tach reading high and did a double take on the pic of the tach. 5400 is still a bit higher than your typical 400. Stout little engine!

It was quite surprising being the first time doing full throttle blasts since we bought the Custom S. Figuring it weighed around 4100 lbs. with a full tank of 93, us two, and tools on the rear seat floor. It's amazing what working secondaries can do...lol! The 350 factory cast pistons are only an ounce lighter than the 400's, so not really any more 'revability' than the larger bore brother.

North mentioned the 350 2-bbl's not being good on gas mileage compared to the other makes 350's, but the HO engine got almost 16 mpg on the highway at 70-75 mph, buzzing happily along at 3200 rpm with it's 3.55 rear gear.
