I've got an HPE 5mil with the lighter full circle ADR crank. Built new in 2017, ran a few tanks of gas thru it and never got it tuned in or running right and pulled it. It's been sitting on the bench since. OEM 454 carbs with V-Force 2's, port matched exhaust, stage 3 porting, etc....a few pics below before the carbs and exhaust manifold added. PM me if you are interested.
