MRL Performance

I bought an unused 340 stroker short block several years ago from a guy over in Detroit. MRL built it for him. Guy got his hemi done and used that. Came with paperwork.

It is now in my Dart. I was gonna just run it. Glad I didn’t.
Took it to a Mopar shop I know very well near me to have then look it over and freshen the Eddie heads that had been on my 360
Glad I did. Nothing but issue after issue.
Lifter bores were too big on the bottoms, ( had to bush lifter bores)main and rod clearances way off, freeze plugs buggered up... zero deck flattops 17 out of the deck... Yada, Yada
Live and learn
Not a good situation
