The 5th character from the left which is a letter..."S" being the LRE engine. "E" is a 318. "T" is a standard 360.
Don't remember the others right off but a /6 is somewhere before the E.

So it's like a car then?

Around here LRE and Warlock are about equally represented.
Hardly ever see anything else.
