Herny When I bought my 1st Chevy truck GM was 4wheel ABS, Ford & Dodge were 2Wheel. I agree it's stupid to go backwards. I think Dodge is still 2 wheel, don't know about Ford.
On the valve thing - leave the valves shut and you don't have the pumping losses, just friction and the heat loss-cooling of the air trapped in the cylinders. The work expended during compression is reocvered on the power stroke - works like a gas spring. I'm going to have to look this up 'cause what I remember is the first ones were carbureted and had a two notched cylinders (like a dog clutch) that could that could either fit between each other or fit end to end depending on alignment and the whole thing sat between the valve spring and the rocker arm. 1978 seems early for EFI.

Why bother with the valve train, other than to make it overly complex. Then again, this is another of the bright ideas from the company that only wanted to put ABS on the REAR wheels of their pick-em-up trucks.
