My friend with the 70 Z28 and carb problems has been interesting. I've had a hard time getting back over to help him with it since we got the Holley carb problems fixed. ie: wrong gaskets and bolts in the wrong holes etc. He told me his oil level was way high. I'm talking over a quart too high. He is meticulous about most things, so something was definitely wrong.
I went over last night and pulled the dip stick......... smelled more like gas than oil.
I was able to light the dip stick on fire. by holding a Bic lighter on it for about 1 or so seconds.
I never knew that gas could get past the rings like that from a very leaky carb, but I guess it can.
He's going to drain the oil Sunday before we have a chance to fire it up again for setting the timing and advance and the fine tuning the idle mixture screws.
Does he need to drain the engine and flush it with clean oil then flush it again with and add new oil?
...or just replace the old oil with clean oil and a new filter? I was thinking Mobil 1 10/30.
Again, this is a 1970 11 to 1 350.
I'm hoping from running the engine and diagnosing the fuel issues the diluted oil hasn't hurt the bearings. We probably have put an hour on the
engine during the many attempts at diagnosing the carburetor problems. During that time, the fuel got into the oil pan.

yes, a close inspection of the oil filter is a darn good idea,
yes, you need a new oil filter and an oil change,
and yes you need to find and fix the problems source thats allowing fuel,
to get into the engine before proceeding any further.
yes, you may have caused excessive wear, on the bearing's, lifters cam lobes
etc if the diluted oil was run in the engine for very long.
be aware it's possible for a manual fuel pump to leak internally and slowly flood the engine with fuel in the oil.
I point that out simply because many people think the fuel might only come from a carb or injector related issue.
yes you stated it was the incorrectly assembled carb,
but others reading the thread may have not considered ,
the other possibility if they are having similar oil/fuel issues
