When I'm choosing a new engine, I tend to look at horsepower, weight, the reputation of the manufacturer and the model. In general, I ignore the marketing labels and just focus on the engine spece. Most of my engines have ball bearings (BB). Some are ABC, others are ringed. I have several OS FSR engines.
Hello Piper,
Well.. honestly you really didnt answer my question, you went on to post about all the different types of motors but you didnt tell me what they mean

I dont fully understand the different labels outside of BB and the CU..
Also the guy at the LHS said that the LS engine is something that he recommended for the trainers becuase it is a light weight engine with a smaller block, Does this make it less powerful then a normal engine in the same class?
