H.O. Engine ??

There was a article about Dyno Tested Engines in the recent issue of Car Craft magazine. They talked about testing H.O. Engines BUT they never mentioned what H.O. means When I was a kid H.O. was a train gauge size, how did that end up in my car??? THANKS DAVE

High Output. Same importance as 'Trans Am" or "GTO", or "Judge", or "Magnum", or . . . . In other words just advertising hype for an engine with a taller cam!

abbreviations can be fun

Hey Dave, what is this one, "OHC"? Not that it applies to anything I am building! I only use sbc stuff that you can find in the junk yard, or Summit if necessary.

HEY TAZZ: That one I know as " Overhead Cam Shaft" I see it in Cars & Parts magazine when they talk about some of the older engines. It is amazing to see a Dusenburg engine the size of your couch with about 100 horsepower. Then you see a Rice Burner about the size of your garbage can that runs 10,000 RPM and put out 300 horse power I am thinking about driving my lawn mower around this summer What do you think????DAVE

Those old Duesies ran a low 5-6:1 compression with little or no overlap on the cam. You could take off in high gear without burning the clutch up on a level surface, so you didn't have to change gears much (no slush boxes before 38 or so!). It would pull at idle, and didn't run many rpms at all, maybe 1500 max. Heck, they would probably drag an econobox around while taking off in second! Crower Cams used an old 1930s Nash straight eight in a rail dragster years ago built to more modern specs. The Nash originally ran somewhere around 7:1 compression, but used a forged crank and rods with NINE main bearings. Crank was rather stiff for a I-8!! Don't know what they got out of it.
