I see a number of issues in the pics that would lead to this -------and , this is something that maybe many of you should consider in your dealings with engines---------
427 block--probably no
oil gallies for the lifters
t & d rockers--probably restricted
oil to the top side
no drain back baffles to direct excess
oil to the individual pushrod/lifter areas
insuffienct rod side clearance with aftermarket crand and rods--reduced oil flow across bearings and slingoff on the cylinder walls and camshaft
Lunati billect rods--no oil spray hole for camshaft/cylinder walls--
In summary---there are numerous things in the build of this engine that dramactily reduce oil to cam/lifter/cylinder wall that contributed to this failure----
