Re: what years chevy motor have z-bar installed
they all have the bosses, but not all of them were drilled. i think they didn't drill some in the 70's when they were trying to save money, but the 94 Caprice LT1 i have on an engine stand in my garage has it drilled and tapped. Chevy II blocks used a different location and i think had a second boss cast in for it..
i think the only pre-LS series Chevy V8 blocks that didn't even have the mounting boss cast in were the GenV big blocks from the 90's and probably the 8100 truck engines. GM sells a bracket to hook up a Z bar to these blocks.
