Can somebody tell me approx what rockers should be firing when the drivers side head is receiving oil on a BB?
Trying to start from scratch on my lack of oiling to the top end. Trying to see if I really do have enough to the top.
Ive been bumping the motor, then priming it with the drill to see when the drivers side is getting oil to the top, but so far havent been successful.

Top end oiling has nothing to do with cylinders firing so if you're rotating it based on firing strokes then you'll likely never see it get oil.
Umm, I may be nuts, but doesnt every crank have to oil in the same position, meaning that a certain set of rockers, or even a single rocker will be in approx the same position?
IE crank spins, feed hole opens, which correlates to a certain rocker(s) position? 
Just trying to get close to the crank position when the feed hole will be sending oil to the drivers side.

Von groove the camshaft and install .040 to .060 oil restricters in the deck face. Some people have luck with the factory oiling to the rocker gear...most don't. I wouldn't own another big block unless it had full time oiling to the top end.

Should be the same as a Hemi right? #8 exhaust valve at full lift, oil to passenger head. #7 exhaust at full lift, oil to drivers side head.

....with a little tweek here & there dependant on lobe sep.
Yep, it was almost at full lift, just a hair before!!

Let's see, here are some notes I had from one BB Mopar priming approximate ranges:
30-10 BTC #1 cyl on overlap, passenger head gets oil
30-50 ATC #1 cyl on compression, driver head gets oil.
The #8 cylinder is 90 degrees from #1 in the firing order (18436572). So a typical cam would have #1 exhaust max lift (lobe center) at 108+/- BTC, and that would put the #8 exhaust about 18 BTC. That matches my observation.

Are you sure? , was a PITA holding drill in one hand & messing around trying to turn motor over to find location for oiling pas/drivers side heads ,Tork is correct in his posting regards oiling the B/RB.

You had me scratching my head here for a while   ..... seems if #1 piston is @ 20* BTDC for pas side oiling then this puts #8 piston @ 110* BTDC , which would put #8 ex valve full lift.

Yes he is for B/RB , but he also said it was the same as the hemi and doesn't the hemi have a grooved cam journal for full time oiling because it has to feed 4 full length rocker shafts ???
Just saying

Yes it is,but the oil sure flows alot faster when the holes in the cam line up with passages going to the head.

Usually you'll see oil at the 10 oclock and 1 o clock positions, thereabouts.

The original race and street hemi production motors had full groove front cam bearings, not #4. the cams where not groove until Crane or one of the other aftermarket cam grinders start offering them on the solid rollers, I think anyways 
But, but, but , Cab how would oil get anywhere if the front bearing was grooved when the passage is thru the #4 journal ?
