I had the Essex in a 3.0E Capri mk1. Matched with a 4 speed on the floor it was thirsty. Long runs at 70-80mph would return 22mpg but cane it and it would drop to mid teens.
Maybe a small block V8 289 cu in. ex Ford or a smaller V8 from Rover or Stag (Buick) could shoehorn in but not decrease fuel consumption (could sound incredible though). A more modern engine as suggested would be an improvement with more ratios available. possibly engine and rear axle from a Jag XJ series as a transplant.

(Holly carb, dual plane manifold etc) These are pretty economical engines if set up right. (Alternatively, as a second option, a K-jetronic ford V6, if you can still find one anywhere)
