Mflint... He used sb to isolate the small block engine from the big block and the 4-banger or even a six cylinder..
Them that knows engines calls em sb or mice engines..
The term comes from the 396/427/454/504 being named GM's RAT engine.. then the smaller engine (sb) would be any of the lighter, smaller engines. I think the Ford 302 would be a great install in a Jeep.
So he was asking why you did not install a small cu in v-8 instead of the 6 cyl... <img src="/forums/images/graemlins/smile.gif" alt="" />
