Looking to replace my 77 440 block and looking for an updated improve block than the origional design. Had my lifter chanel pluged off and was going to go to a external oiling system as well as a girdle on the mains before I dropped a valve and can't bore any more. The old 440 design had a weak oiling system and unless you upgraded your bearings were toast after 6000 rpm. Have seen alot of block with new strenght and oiling designs but have also heard they are not all what they say. I am talking about Indy maching not being done right and need additional work. Not sure if mopar performance new blocks have made any improvements (reasonably priced), they don't really say on there home page. Have heard the best remarks about World, but very pricy.
Does anyone have firsthand knowledge or any info that will help me make a decision ?
