" I remember the sheet metal shop my Dad worked for buying a few of those carbureted V6 trucks, 1/2 ton shortbed 2wd with the manual trans, very doggy performance."
California Emissions Package engine ? ( ) . whenever I hear "doggy performance" , I automatically think , Must be a California-spec engine !
