wierd stuff, maybe not
Anyways, i built my 408 like 2 months ago, last week i changed the camshaft springs manifold, and lifters, the engine ran great before and still does, i changed the oil, but a friend helping me used 8 pots of oil instead of 7 overloading the engine, i figured what the hell. I turned on the engine and its burnning ALOt of oil(blue smoke comming out of the exauhsts), but the engine is runnig great, tire burning good preasure, good temp and no pinging, can the oil overload really cause this? i it doesnt sound logical to me....

I have seen engines burn excessing oil when over full. It is not good to keep the engine overfull with oil anyways. The connecting rods and crankshaft counter weights can slam into the oil, splashing it all around, which creates a lot of drag on the rotating components in the engine (and splashing oil where it doesn't need to be), and it can create excess wear on the oil.

i recomend to check the oil and know how much oil you need to be on the (xxxxxxx) target. I also want to ask you a question. I'm rebuilding a 400 with .030 over and doing a complete rebuild. I have a new stock style oil pump, and shaft. Should i go with a high volume oil pump or i'm still ok with the stock one. Motor rarely gonna see more than 5000 rpms... and less 5500...? Street 400 in light vehicule , rwd. Torque is what i'm seeking for at low rpm's with high rear end ?

hmmm yeh they vary acording to the pan size, mine initially worked fine with 7, the oil change was after the break in procedure and didnt change the filter, i will remove 2 quarters 
, anyways mustang if you made the cleveland fix on your bearings theres no need for the hv pump, if youn didnt like myself use it.....oh remember to use a hardend pump shaft..

Its pretty famous, dont remember well but it restraind some oil going into the camshaft so the main bearings have more oil, you had to drill or block some oil pasages ssomewhere..
Anyways, i removed the excess oil, its still smoking oil thru one of my exausts, could it mean teh high oil preasure damaged something? maybe a piston ring? valve retainers? maybe just opened ints way thru the intake? or mybhe theres some oil still left in the combustion chamber? it smokes more at iddle that by revving it, any ideas?

Yeah i know mud rat, but very little hp, not enough to be worried about.
Anyways, I removed all the spark plugs, the side that was foaming alot had all 4 spark plugs with alot of oil, the other side only 2 had oil and very little, I cleaned them.
I took the intake off, it definitivley was leaking oil into the intake ports. I threw away the valley pan gasket and installed seperate gaskets, the valley pan gasket was the original one and was recked beyond use... So the engine ran way better this time and almost no smoke is coming out of the exauhst, to see the smoke you have to revv it alot. Before at iddle it smoked ALOT and way worse revving it, so i asume i fixed the problem nad maybe still have some oil left on the glass packs and the cumbustion chambers... hmmm could oil take a while to burn? or could i have something else going on?, i mean really little smoke is coming out and its hard to see, any experience on this?
Im still woried my rings went bad for the foaming, Thanx

Pure oil doesn't like being burned in gas engines. I had a couple of lawn mower engines that had bad oil seal rings, and during idle, the combustion temperatures were so low that the oil getting past the rings would just build up until you went full throttle again, and blue smoke would billow out at least for 10-20 seconds then turn to a light haze. Just watch your oil consumption, if it isn't changing then it is just most likely oil still stuck in some places that is clearing out.

I've known some engines that would blow out the top 1/2 to quart of oil and a guy learns to run them a bit low. I'd rather be 1/2 qt low than high for sure. might ck plugs if it does begin to run a bit off....they don't like oil.
