Cast iron world RB block mods for pushrod oiling - 11/24/14 11:28 PM
I have a complete world products RB engine with B1MC heads that's I want to convert to pushrod oiling. I know that I need different pushrods and lifters. I'm going to switch to T&D paired rockers to. What needs to be done to the block?

Other than block the oil feeds to the heads .... which you probably don't really need to do ... nothing that I am aware of.

Curiosity leads me to ask, assuming with your cylinder head choice this is a compitition engine only, correct? If so why would you want pushrod oiling?

I want to run a larger cam/ spring pressure and don't want to chance the Koffel's rockers that I have. I'm pretty sure the only way to oil T&D paired rockers is by the pushrods. I do not want to spray bar oil either.

Just drop the new lifters and pushrods in place and you'll have pushrod oiling. I use pushrod oiling + valve cover oiling for my 514 engine.
I have Jesel rocker arms and the pushrod cups burned up with valve cover oiling. I added pushrod oiling using Crane roller lifters and the problem went away.

FWIW....I have been using T&D paired with Trend pushrods for eons.....no failures.
I depend on the rods to oil the lifters and my spray bar is used to cool the springs with the splash lubricating the rockers and pushrods.
A pushrod full of oil is going backwards in reducing component weight....its difficult to get a stable pushrod that is also desirable weight. Food for thought.

Thanks for the info guy's! So any roller lifter that's set up for pushrod oiling? I currently have Isky red zone so I would probably get these again with the oiling option.

You will need to restrict oiling with bushings. Otherwise you will have too much oil up top. So....I would bush the lifter bores.

most pushrod company offer restrictor ends in the pushrods..... a .030" works perfect in most combos...
