Dipstick Dilemma
I'm swapping an LS2 into my Z06 and intend to reuse the original dipstick. The various nearly dozen LS engines share so much else, is it safe to say the level placement and reading on the stick itself will be accurate to the new block on the original batwing pan?
I don't want to think I'm low and end up frothing with too much oil, or think I'm high and end up burning.

I would say yes, you shouldn't have any issues but I don't have anything to base my opinion on other than your swapping LS engines and it should be fine. I would post over in the Tech Forum and I bet you get a reliable answer. Let us know.

Correct. The '97-'00 used a straighter, shorter, and, imho-more accurate dipstick, than the '01-'04 models do, 2 different part numbers. Also, you must match the actual dipstick with the dipstick tube. You can't run the older dipstick in the newer dipstick tube, and vice-versa. I also believe the later models have a half quart less recommended oil fill than the earlier models. IIRC, the early ones recommended fill is 6.5 quarts, and the later ones are 6.0 quarts. Don't quote me on the exact amount on the later models, but I do know they have different recommended fill amounts. ALL models will gain some power by running 5 quarts. This should ONLY be done in straight line drag racing, if you do decide to do that. I found out by accident, when my newer style dipstick read wrong, or I read it wrong. But I picked up 1-2mph!! I don't recommend doing this, but my oil pressure never dropped. NEVER try it when road/oval/autocross racing, or YOU WILL damage the engine when the lower oil level causes the oil pump to cavitate in turns.........

But why would I do that when I can pose another question about whether the LS2 dipstick would read accurately on a batwing C5 oil pan vs an LS2 pan? (I'm totally just being a d

Why wouldn't the dipstick be more associated to the oil pan than to the engine? Pretty sure the crank centerline is the same across all Gen. III and Gen. IV engines, so the controlling element for oil height would be the pan.
