12 second 340

i hear some people say they had trouble with them and i personally know alot of people with alot or runs on them with no problem and mine is fine.. its like everything else i guess you are bound to get a lemon weather its a mopar motor or a top notch shop that does it.... and to tell you the truth i hear more complaints about the actual crate motor then i hear about the short block. plus the 380 horse motor is about $900 more and doesn't use alum heads.... all stuff to look at...but hey everyone has their opinions...


if your affaid of the actual short block then just copy it... find a used 360 buy a set of kb pistons and assemble it yourself.. could probably do it for close to the same price as the mp short block....
