Does anyone know if this block provides oiling via pushrods to the valvetrain as I hear that the Hemi's are weak on rocker oiling. Any help appreciated as I am building one of these blocks and intend to use a solid roller + stage V roller rockers.. -------------------------------- Darren Beale Keith Black Racing Engines®

Michigan	Pushrod oiling can be used if desired with no problem, but in as delivered form the Mopar Performance/World block is configured to oil through the rocker shafts full time. Oil goes through through a passage that intersects a main galley, and it has a restrictor near the deck surface (It does not use "timed" oiling through the cam bearing like a stocker).

I noticed that the lifter bores are bushed and they have tiny oil holes in them.. so I was just checking if this was for lifter oiling only or for oiling through the pushrods to the rocker gear. I deciding rocker gear (Stage V/Jesel)and heard that the Hemi rocker gear can have durability problems in the pushrod/rocker cup area due to poor oiling. Do you know if the Stage V rocker system uses pushrod oiling ..or are they oiled through the block..? Thanks! -------------------------------- Darren Beale Keith Black Racing Engines®

It's only a problem with street engines with solid roller cams. These engines see a lot of idle time and the lack of pushrod cup oiling along with the higher spring pressures will cause problems. The best way to handle this is pushrod oiling for the pushrod cups and through the block oiling for the rocker arms. Use a large oil pan because at higher RPMs there's a lot of oil up top. Bushed lifter bores are the best way to go because you are assured of not using too much oil for the pushrod oiling, and the bushed bore allow using several different lifters.

Mr T2U master M Joined: Apr 2005 Posts: 4,923 new berlin wisconsin	the guy who built my 624 hemi that had a large cam used oil thru push rods to lube the push rod cup area. he has been doing that for over 10 years on street stroker motors that see lots of low rpm's. perception is 90% of reality

Milodon gear drive. Std cam dia. Manual trans show car/limited street use. Idle 1500rpm so should be some oil thrown around. Deciding valve gear .. reckon Stage V will do but need to know if the World Block can be modified to pressure feed lifters..? The lifter bushings appear to have very small holes in them (pressure fed?) Could I also use Smiths Bros p/rods + Jesel lifters? Any help appreciated! thanks again -------------------------------- Darren Beale Keith Black Racing Engines®

The current issue of Mopar Action (October) shows the various lifter options in an article I wrote. I'd suggest the Crower 66255H lifters. They are very high quality and provide all the pushrod oiling you need. You don't need Jesels for this application since the Crowers also pressure feed the roller just as Jesel does. The bushed lifter bores are the preferred way to go. The World block is already set up for providing oil to the lifters and the small hole in the bushing is more than adequate for the amount of oil you need for this function. You won't have to keep the idle RPM up at all. You shouldn't have any problems with that small a lift cam. Smith Brothers do all my pushrods. Great company and fast too. Just make sure you use the newer thick wall 3/8" pushrods, hardened and the ends drilled for pushrod oiling. Here's the ones I used: Smith Brothers NH312B-CB, 3/8" dia., 5/16" ball & cup, .120 wall, Hardened with oil hole. Intakes were 10.84 and the exhaust were 11.75, but you should always measure what you need before ordering pushrods. As to the valve gear, I use Keith Black or Dechellis rocker stands (www.dechellismachine.com). I always use Dechellis for the rocker shafts. Use the Stage-V rockers and you'll be very happy with the results.

It must be in the post (I live 1/2 the world away in Australia). Darren PS: What's your book so I can get it?

The book is called "How to Build Max-Performance HEMI Engines", and you can preorder it directly from my web site www.fastmanefi.com I will autograph all books ordered from my web site. Shipping cost to Australia is an additional $11 so your total would be $35 rather than $24.

There's been a lot of innovation in the last few years on the Hemi it's great to see a book that can help a newcomer like me navigate my way around the options & combinations! Thanks again Rich, (Chicago=great city) -------------------------------- Darren Beale Keith Black Racing Engines®

Of course I had no idea at the time that Grand Spaulding Dodge would be such a landmark. I lived very close to that dealership and visited often. I was hanging out at a local drive-in called "Skips" when I heard my first high compression Hemi pull in that was recently purchased from Mr. Norm. My publisher pulled the story out of the book because we had to get the page count down, but it was a special night for me that I'll never forget. I think I'll place a post in the General section and see if any Moparts members remember Skips.
