More SBC Questions

StockerRook · 08-04-2011, 10:46 AM

Have a couple of questions regarding my LT1 stock eliminator motor we are trying to finish. Any help is appreciated. The motor has Sherman lifters and stamped rockers.

1. Does a Small block require oil restrictor plugs in the back like a Big block does?

2. Which way should the oil hole on the side of the lifter face? (Inwards towards the cam or outwards towards the exhaust port)

Thanks

Chris

Usaully I prime and see how rockers are oiling if they are oiling too much then I restrict them small block uses same restrictors as big block, I did'nt see what type rocker you are running roller rocker can get by with less oil than stamped.
If lifter is'nt offset you can install either direction as long as recessed groove on lifter is lined up with oil galley it will work .

Please dont shoot the messenger just cause he has an opinion. I havent used oil restrictors for at least 5 years. I let all the oil go to the upstairs and cool the springs. I then spend a great deal of time making sure that I can return all the oil to the pan as quickly as possible. I polish every area and enlarge all that I can. Especially look at the area on the block just under the return holes from the head. I do not use any wire screens as I have found that they restrict the oil flow. I drill a .312 hole at the rear pan area in the block to redirect flow down the drivers side to keep it off the crank. In my humble opinion, oil is just as much a coolant as water is, so I channel it to where I want it to go. I also run a deflector pan under the intake to keep oil off the intake and to keep lifter from popping out if I break a push rod. Dont break many using .120 wall 7/16 any moe. I try to use a valve spring that does not have interference between the inner and outer springs and or dampner (if I can stay out of surge or harmonics). Both contribute to heat and shortened valve spring life and hotter oil. Boy I am glad I brought this up so yall can holler at me for my beliefs but I already heard most of it from my x-wivessss so I can take it--I think,

I try to stay away from messenger shooting unless they really need it. I don't see where your message requires any shooting.LOL.

Restricting the lifter galley oil is a practice carried over from the "old" days.
It is not done at my shop any more. 30 years ago, yes! What the previous post (Reed) pointed out is a good explanation. The things that made restricting necessary in the old days have been vastly improved by modern technology. Now, other places in the engine need the oil more than the bottom end did in the "Old days". That last statement means the valve gear needs the oil to live longer.

I'm with Adger ( Whoda thunk?) I have not used restrictors for years. I used to tap the oil passages (5/16" USS If I remember correctly) and screw in drilled Carter carb jets as restrictors. Bottom end oiling in a sbc is no problem at all. With 1.8+-1 intake rockers .800"+ intake lift and 1000+ lbs spring pressure over the nose, pushrods need oil. Myself and many others went through a period of burning ends on pushrods a couple of years ago. More oil up the pushrods cured mine. I still modify my intake pushrods for that.
