oiling issues on my motor. hey guys its not a chevy but i figured the same principles would apply.
im having some ussues with my 440 equipped dodge charger.
ill give you a little background about the car first;
i bought the car equipped with a virtually stock 1976 440 and 727 auto in place. with in a few weeks the carb gummed up and i decided to put on an aluminum intake and new edelbrock carb, in the process i saw that the cam was scored so i replaced it with another flat tappet hydrolic cam (just a bit hotter than stock, little did i know i needed to add some E.O.S. or use heavy weight oil) broke the cam in like normal and proceded for a few weeks taking the charger for a few trips around town. later i started the body work and such so i have put less than 30 miles on the car since the cam change...i have always had about 80 lbs. oil pressure on a cold start and about 60lbs on a warm motor. long story short:
around thanksgiving i started the car, and with my eye on the guage the oil pressure fell from 80lbs to 0...then up to 60 back to 0...then 40 to 0 and finally just stopped. so i stopped the car and put a new mechannical gauge on it, same thing.
i pulled the pan and there was a ton of sludge, cleaned the pan/changed oil and filter/ cleaned the pickup... this time when i started it no oil pressure at all.
i used 20w50 oil, no pressure.
i replaced the pump, no presure.
what could it be guys? i never checked the oil pump drive but i assumed it was fine because i had oil pressure in the begginning.
did i suck up some sludge into the motor?
did i finally wipe the bearings?
any help would be greatly appreciated.

Is the distributor fully seated on the intake? My hold down was loose once and the distributor walked up and the oil pressure hit the floor. I would make sure the bottom of the distributor drive is seated to the pump shaft and that the shaft is in the pump. You should be able to tell easily if its not because the distributor wont seat fully on the intake. Try and clean that sludge out of the pickup/pump if you can, that could be your problem too.

You have spun a bearing, plugged up an oil fed hole with debris or the gear on the distributor shaft is spun.
We have built many 440’s; if you check the April issue of Popular Hot Rodding you'll see a 68 charger with one of our motors in it.
If we can help give me a call.
