Default Engine Oil Level - 1970 454

This may seem a unusual question, but during my restoration the old engine oil dip stick was thrown away (old rusty chrome one), I and I have fitted an "original" Ecklers one to replace it.

However just a little wary, although convinced its the correct one for my car, bearing in mind the consequences, just wanted to ask how far up the oil level in the pan should the oil approx. be i.e 6"-8", from the base of the pan well (lowest point). Or if you could measure it what distance do you have on your 454 dipstick between the top of dipstick entry hole and the mid oil level on the this stick.

I put in the correct amount of oil and it all seems about correct but would be very grateful just to put my mind at rest if any one can answer this before I start the engine as the final point on my restoration.

Stay safe and well
KInd regards
Paul

If you added the correct oil volume, and it produces the correct level on the dipstick, you are good to go.

The only concern I would have is that the length of the stick AND the length of the tube must match. A "correct" stick needs a matching "correct" tube in order to read properly. There are different tube/stick pairs for different applications.

While waiting to see your photo, I took a few measurements of my oil dipstick tube and oil dipstick. I still have the original parts on my '71 LS5. My measurements are approximately from where the oil dipstick bottoms out on the dipstick tube.

Thank you so much for going to the trouble of measuring this up. I will be in the garage tomorrow morning and will take some new photos before I post them to compare the new stick and tube I puchased to this in the hope this could be useful to other members.

Stay safe and well

Many thanks to all; no photo from me will not help, as I got very similar measurements with an oil level that will be around 1/4" higher.

Many thank for the ressurance I was pretty much ok with this due to my source of dipstick and tube from Ecklers, adding the correct volume of oll as per the manual, and then spinning the distributor gear to get oil circulating and seeing pressure on the oil gauage.but still had a nagging concern as I did not have the old stick to compare. I will now start the engine with confidence (and hopefully after compelting lots of work on it the engine will now power up after just a few turns!).

Kind regards
Paul

I get where your coming from on this.
the ‘68 I brought home in February has the L68 427. I changed the oil and filter putting in 5 quarts. The manual said the engine takes 6 total if I read it right, one in the filter an 5 for the pan.
I put 5 in and fired it over let it run and checked the oil level, it was way over the full mark !
wth ???
Then I notice there’s a scribed mark coinciding where the 5 quarts lands on the stick. Obviously the wrong stick. I matched up the stick to one from a ‘67 427 in Corvette Paramedics showroom and the scribed mark was indeed where it would be. Got a new proper repo stick from Zip and 5 quarts is right at the full mark. Still, wasn’t it supposed to have 6?
When I was at CP I also took a hard look at the pan on that engine and it was the same.

I guess what spooked me was when I sourced the replacement a place I use for spares said they dont supply dip sticks any more due to a customer problem after supplying one that turned out to be incorrect. Hence whilst sourcing from a reliable route thought (even thought it felt over cautious) it was wise to double check.

I will say the one I checked my stick against was a ‘67 427 Tri-power which is the same as my ‘68 Tri-power. The tube was the same as mine too so I know my repo stick is correct. The sticks button color is key. Mine uses the one with the white button. Yours uses the one with a red button.
The Zip # is “OP-126” 70-74 454 red button $15.99.

Don't forget the size of the oil filter can make a difference on where the oil mark is on the dipstick.

Very true.
I put a NAPA gold filter on mine which is made by Wix. Wix is probably the best filter available. The one I took off was some odd brand but was a long filter, the NG/Wix was short. Anyone know the Wix or NAPA gold number for the longer larger capacity filter ?

There is a Wix #51069 which is 4.33" tall and a #51061 which is 5.178" tall. there may also be one that is even longer like the old AC PF35 which was about 6" tall.

Longer filter costs more and is harder to find. I doubt anyone here has enough dirt in the crankcase to require all the extra surface area. The engine wont live any longer or make more power. Just something to consider.

it’s not so much the extra filtration it’s just a cheap quick way to increase capacity even so slightly.
In days past Wednesday run a filter relocation kit and double filters to add a quart to the capacity.
