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 ?

I can tell you your info is seriously of on thefactory oiling system's capabilities. But if you're going to the next level, a good block (aftermarket) is a good idea. I wouldnt trust anyones block machining except the KBs. Not firsthand knowledge, but a bit of second. I also am very picky. The older MP stuff you need to be very careful about bore size. The castings can be way shifted, making max bore sizes smaller than advertised. I'll let the other guys chime in.. And you may want to move this to the race section to get reliable firsthand info..
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Let me simply rephrase the question, when I am not so sleepy and can write a coherent sentence. what is the best aftermarket 440 block on the market that has an improved oiling system.

Koleno or the new MP/World block . they both have their differences but they are the best irons blocks available .

Your right DVW the valve problem was unrelated to the oiling problem, but did spin a bearing before the last rebuild by exceeding 6000 rpm. After spinning the bearing went to a 500 stroker crank and full roller, plugged off one lifter galley to divert more oil to the mains. Had held up pretty good until I used the 440 source roller rockers and they didn't hold up:(Am using one of there lightweight cranks and rods and have no problems) one of the roller shafts wore loose and the roller tip came out depressing my valve keeper and clank. Learned a good lesson about $200 roller rockers. Anyway I am going to be putting out about 650 HP and would rather get a more durable, better enginered oiling system to start with than block off galleys and put main bearing girdles on the block, ect. you know what I mean ?

the world block still oils the cam bearings from the main bearing saddles but they don't feed the rockers thru the #4 main/cam journal , the heads are fed directly off the main galleys so you need to put a restrictor inline , the blocks are tapped for screw in restrictors.
if you go to the new products section and find the thread about the world blocks you will see it all .

if you spun a bearing, i doubt it's because of the factory design of the oil passages. we routinely build engines using the factory blocks that run way above 6000 rpm. proper machining and inspection along with the proper oiling modifications, which are easy to do, will solve those problems. 650 HP IMO is well within the limits of a stock block. if you need any advice on oiling mods, most are in the archives on this site or you can PM me. sorry to hear you learned a lesson on those cat rockers the hard way.
