Setting up dipstick

If your pan is same depth as the truck pan use the truck dipstick and drill the hole.
if it'a the same depth as a stock A body pan you'll probably have to re-mark your dipstick.
Some folks with deep, drag-race type pans put too much oil in them, the point is to get the oil away from the spinning crank, and still keep the pick-up covered.
Thank you. I think my oil pan is either the same or slightly deeper than a stock a body pan ( I've never seen one ) on the shallow part ( the main body ) but I'm pretty sure I figured out why it looked like the dipstick physically wouldn't fit the original pan on it, but I didn't have the old oil pan around and it had been so long since I took it off I couldn't remember what it looked like. I now think the housing part of the pan (the main body not the sump ) on the truck rear sump oil pan that was on it is deeper, and that's why the dipstick fit without bottoming out for that application. The kevko I have now is, of course, an a body center/front sump. For a while I couldn't figure out why my dipstick was so long. I have read that all dipsticks will fit. I searched but I couldn't find any more detailed information about that. I couldn't figure out how my original dipstick would have fit the original truck pan with a rear sump because I thought main body of the pan was the same depth. At that point everything looked wrong for everything and that's why I couldn't figure out if I was supposed to run some sort of special dipstick, not the one I have.
Now I can drill the slosh guard ( or bracket or baffle or whatever it is ) for the dipstick I have and I will fill the oil pan by itself to see how how many quarts I can put in it without it getting too close to the crankshaft. Then when the oil pan is on the engine I will put that amount of oil in it ( and also mark a quart low ) and re mark it.
