Yes Vis a Vis, I remember the Vega well. All aluminum block with iron coated pistons running in aluminum bores with no liner. They weren't bad for an economy engine at the time if you yanked them apart, sleeved the block and replaced the pistons. I did the best thing, drop a 300 hp V-8 into them with a 9" Mustang rear end. I got 22 mpg at 70 and 20 in town with the V-8 and ran like crazy. The stock Vega engine didn't get near the same mileage I did, nevermind the performance.
