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.
