Red face SBC oil

i have a unstarted hybrid 327(350 block, 307 crank)
i got one of them there oil priming tools from autozone, i put it a drill, it frist spit oil out the sending unit hole, then after pluging the hole with my old oil pressure gadge it read 25psi when i was winding my drill out till it smokes, switched drills, 25psi, both time no oil came out the rocker arms, i tryed the same idea on the old motor, same thing, is this normal? is it safe to start

i have been told 1400miles is the break in period.
a local mechenist told me i only need to run it for 500miles, after the cam break in and 500 miles the barings and rings should be seated, how much of this is true?

thx camaro76

ITS POSSIBLE OIL WON`T COME OUT OF THE ROCKERS IF YOU DIDN`T SOAK THE LIFTERS IN OIL ,BUT IF IT`S SMOKING DRILL MOTORS THERE SHOULD BE GOOD OIL PRESSURE JUST WEAK GAGE AND DRILL.

Normal, lifters don't pump until they are lifting and are properly preloaded.

Good advice from the machinist...

Good luck with the fire up!

Look in the engine forum, there's a few good ways to adjust the rockers/lifters there (type hydraulic lifters or lifter adjusting as keywords). As far as break-in both of the suggestions are good ones. You want to avoid lugging (full throttle starts), and you should watch the RPMs. If you take it on the highway (sustained RPMs), every so often let off the gas and then back on. This will allow the rings/bore to lubricate and seat better (you won't be "burning the bore"). Myself, I beleive once the cam is broke in, so is the motor. However, it's good to be cautious if it's your first motor. I have had freinds that had problems with rings seating from just letting it break-in with the cam break-in like I do. But then again, thier driving habits had alot to do with it. I would have to say there's nothing wrong with being cautious, it's better to be safe than sorry. When you have done a few motors you will better be able to decide how you want to break them in. Go with the ring manufacturers suggestions, as that is the biggest part of break-in apart from the cam. Race motors aren't ran for five hundred miles before a race, but they are put together by pros.

reading over the nice links left by CL(thx BTW) i saw something in there about running the drill for 20min? i ran 2 diffrent drills for less than 5min east and they both smoked, these have yet to fail me befor, and it hard to believe that 2 drills gone bad at the same time.
i also saw priming a fuel system, this is a new idea to me please explain, or show me a link

Not sure but I allways use a gutted distributor.I think theres an oil passage that the distributor housing blocks.If thats true theres were you oil pressure is.
As far as babying it I stay right off them just drive it like its Mom's car.And keep away from high rpms would be my advise.
I've got a new heart this year to. So I may put a block of wood under the pedal for the first few miles cause I turn into an idiot sometimes.
