That is because there is no substitution for cubic inches. All old
hotrodders and cropdusters are aware of this as are Dutch insomniacs.
<g> The smaller engines show good figures in the brochures, but I think
they are just some sort of cost cutting for the manufacturer and really
don't deliver as advertised. The final gearing to the road is what
determines the running rpm for the "sweet spot". I happen to run 454 ci
Chevrolet gasoline engines in my pickups. Sweet spots are the same as your
Ford. Mileage is, of course, less. Since you raised the cost of diesel,
cost is the same and I don't need a stepladder to get in.
Hot and humid here today. An air conditioned shop would be nice! I am
finishing the top overhaul on my sprayer. 1340 ci by the way, if you
remember the AT-6. <g> This thing is costing me an arm and a leg. I may
be clear out of the collecting business by the time this is all over.
