LAS = 1953 car with Powerglide & power steering
115 hp

The "Thrift King" 235 3-speed that year produced 108hp.
I do not know if it was a high pressure engine (like the Blue Flame), or a low pressure engine like the big-truck 235.

Hotrod Lincoln and others might comment/speculate on hp of that engine with mechanical lifters and solid cam.
