Ok I'm hoping you guys can help me. Over the winter I installed some indy alum heads, I started the car today for the first time, it fired right up, little noise from the valve train, no big deal. Trouble is after a few seconds I usually have oil pressure, I waited a little longer about 15 seconds, no pressure. I have mechanical gauges and it takes about 5 seconds to get pressure every year on the first start, takes time to fill the line to the gauage. today still no oil in the line at all. I'm thinking the oil pump just went out? any ideas, or suggestions? Motor is a 440, no issues at all last year.
pop a valve cover and see. did the valve train quiet down, if so I would suspect your gauge or the line clogged over the winter.

pull the dist and have a look, maybe spin the pump with a drill.
this would be my next step, with the cover off. or pull the coil wire out and crank it while watching for oiling.

Pull both covers and check for a loose rocker and (bent) pushrod.
If a pushrod is somehow forced out between a lifter and rocker, the cam will knock the lifter up out of it's bore and you'll loose oilpressure.
There will still be a weak flow of oil near the crank but no pressure higher up or at the gauge.
Has happened 2 or 3 times with me over the years.
This, or the oil pump's pressure control valve is hanging open. Same deal, some flow is present, but hardly no pressure.
 I had forgotten he had changed heads. there might even be a pushrod not put back right.

ok my bad guys sorry. I was lazy and pulled the drivers side earlier, there was oil, that's the side I put oil in. I had a brain fart. I just pulled the passenger side, bone dry. all the pushrods and rockers are fine.

ok I tried turning the rotor by hand, it doesn't turn.
well, if it had turned freely your issue might have been as simple as the oil pump drive or bearing. you're gonna have to pull the dizzy either way. get your #1 cylinder up to the top, pull the dizzy and check the oil pump drive. if all looks in order then it's your pump. the only other thing I can think of is the oil holes in the heads and gasket aren't lined up. and that, my friend, would suck! but it is the only change you made.......

If I'm reading this right the oil you saw in the one head was oil that you added thru the valve cover filler neck? So both heads are dry right? I'm thinking drainback on the filter/suction side. You might pull the filter/cover the filter round flange with a baggie & drill prime it CCW. If still no go I'd pull the pump & see if you can dribble some oil into the in/out block holes to try & help it prime & maybe even pull the pump flat cover & add a bit there too. the heads oil with #6 and #8 at TDC. turning till the rotor is at #8 then pulling the dist/intergear & preoiling right there will take care of that one and then moving 3/4 turn CW to get to the TDC slit (#6 compression) will take care of the other head. I forget which is to which bank but you need both oiled. holler how it goes. EDIT when squared away turn the crank slightly CCW to 15 BTDC (#6 compression) and set the magnet dead even with the reluctor tooth and the rotor under the #6 plug wire cap & clocking the inter gear anywhere so the wires are in their OE location is a good plan (iirc #6 is sideways toward pass fender but check on that). some dists have different top rotor to bottom tang clocking to each other (than an OE dist)

They are Indy 440-sez. I pulled the distributor and the shaft, the shaft looks fine, Its not stripped. I had to order a priming shaft, I should have it tomorrow? I'm gonna prime the hell out of it and see what happens, I will let you guys know.
you are a patient man!  I would been rigging up a cutoff screwdriver or something and really making a mess out of things! kudos for doing it the RIGHT way...
