old article in Mopar Collectors Guide April 1999 gave up some info how it was built. 040 over , ported 2.02 J heads , stock stroke, headers , 727 with 8'' 3500 converter, 391 rear - 323 gear when we got it. It had a 6 pack with nitrous. Air cleaner lid just did touch hood causing minute rub under hood. Removed the plates because we never used any nitrous. Taking it apart we found the info was correct - it matched what they said. Ran well for us for 7-8 years until it started fogging things up waiting at lights the end of 2022. Had to do something - it was a little embarrassing. Broken rings in every cylinder. Then & now pics . Too much party for # 5 - he was sleeved.
