I'd call any engine that provides less performance that it technically
could, using available technology, (using 91 octane gas) due to its
swept to total volume ratio, a "low compression" engine.

Why do this? So you can buy gas that isn't marked up much and burn
more fossil fuel and make more polution?

my guys tell me. A high compression motor is just a better motor in
every way. Corky?

What do you consider to be a low compression engine? My understanding
is that many current engines sport 9-1 compression ratios these days.
Don't think anyone offers a 7.5-1 anymore, but I stopped being an auto
mechanic in 1983, and don't follow the auto industry like I used to
anymore.
