350 chevy cam bearings

could any one please tell me how the front cam bearing go in on a 350 chevy 2 piece rear main seal,the luck i have been having lately just like lines from peanuts with the big black cloud i am really :confused: i see some with the oil hole lined up with the oil hole in the main and than i read that it goes in at 12 and 4 so would that mean that the oil hole would be pointing up to the intake at 12:00 o clock and the other hole would be at 4 o clock not to sure whats right whats wrong and with that big black cloud hanging neer don't want to take the chance any help would be well appricated thanks :HMMM: :confused:

on a chevy sbc it is a fully grooved cam housing bore so you can put clock it any place i put them in at 4 to 5 clock i put it in. at 12 you do not want the number two hole the cam will load down and more oil will pee out at 12 o clock

that great so 4 o clock and 5 o clock for the front bearing,lets see if i get this right :HMMM: so would that make 5 o clock line up with the front main bearing oiling hole :HMMM:.thanks again for all the help,club hotrod rocks:toocool:

i off set all of them from the main oiling hole at 4 to5 on the front one with the two holes i do not worry about the other hole just put it so it not at 12 at . if you want if you line it up on the main oiling hole the other hole will be at the fuel pump side i like the oil holes off set so the oil will ramp up under the bottom of the cam with the oil hole in the stock place it sill works but i just move all them this way on hp use or just line all them up thru the main oil holes from stock use and the other hole will be at 9 and one at 6
