i am trying to find out info on the"The Problem" You know the one - where the starter bolt holes were machined too far from the crank centerline. "The Problem" occurred in several production runs in the late '70s and early '80s. You can usually spot it by the evidence of too little casting material around the outer starter bolt hole>>does anyone what engines had these problems? was it just 350?

 

All Chevrolet motors.... 6-cyl, small block, big block, all of them. The 454 in my 74 Caprice convertible had it so bad that it literally broke the starter right off the block - in a couple of pieces - when I put a new really good battery in it the day after we bought it.
