I have built a 383 and stuffed it in my Fiero. The donor engine did not have a good oil pan or dipstsick. I used a cast aluminum oil pan of unkown size. To mark a dipstick I need to know how many inches below the bottom of the block should the oil level be?
Can anyone supply this measurement?
Thanks
Drain the oil. Load 5 quarts into the oilpan. Mark the dipstick. Use the edge of a file to make a line on it.
That assumes it is a 5 qt oil pan. What if it is a 7 qt?
A file is a bad idea, it will break off at the file mark. Use a vibratory marker.
You really think there will be that much stress applied to a dip stick hanging static in oil? I would think a file mark would be fine in this case, but maybe I'm wrong.Quote:

If you read my original post I explained the pan is an unknown size. It is not stock so I do not know if it is 5 QT or 7 QT. As the V8 is in a Fiero I can not pull the pan unless I pull the engine and cradle and the n remove the engine from the cradle.
I ahve decided it is a five qt. I measured the pan as closely as I could and got someone to send me the dimensions of a stock pan.
Thanks for all the suggestions.
the dip stick should read the same from 5 to 7 or 8 the stick has nothing to do with volume of pan the stick keeps you from over filling or running low if your using a stock dip stick leve would be the same no matter how many QT it takes to get it to read fullQuote:

If he bought an aftermarket dipstick & tube (like a LOKAR) he's wanting to be sure it's right. One way, like you point out, would be to get a stock SBC tube & stick, fill it to the "full" mark, and then switch to the aftermarket dipstick/tube unit and mark it to match.Quote:

Of course he could take a dipstick and put it into a known stock motor/pan with a fresh fill of oil and mark it( or note where the oil level came to) and then put that dipstick into his pan and not the differance--adjust from there
When the oil runs out the header, it's full:D
Roger,
You have it right. :) Engine core had no dipstick. Oil pan is from ebay, cast aluminum with ribs and fits well. Bought more than a year ago (4 year project) and I do not remeber if it said it was stock size. Due to engine location in a Fiero I had to purchase a Lokar flexible tube and extend it to be reachable. I did not think about marking the dipstick until I had already extended the tube.
Thanks to all the suggestions I have figured it out. Pan is a stock 5 qt so I will fill and mark.
Thanks to all. ;)
Not the stress, its the vibration. Take an old stick and put a scratch across it. Bend it a few times in the vicinity of the scratch and see where it breaks. We trashed a bunch of replacement sticks before we figured out why they were breaking off.Quote:
