OK crew---------educate me please. Suppose I was looking to buy an early '98 QC with a 12v motor. I have searched the forums and have learned that the late 12v's have the same block as the 24v. Am I right or did I miss something? I also learned about the dreaded "53" block however overblown or not the issue with this may be. I assume then that this is basically a 24v issue with thin block castings right? I can't tell from the posts when this block began to show up in production. Could y'all help with that? Did the late 12v'ers which supposedly have the 24v block potentially have the same problem? How 'bout if I just buy a '97 without the 24v block? My history is dusty here but dodge did introduce the Quad Cab in '97 right? If I buy used I must have a Quad Cab so right around this model year is what I'm looking for. Nothing particular against the 24v'ers but I'd be partial to a 12v if I bought used. Thanks all.
