L30/M20 cars

[RAfbody]

Are there any documented cases where a car built in July could have been a L30/M20 without the 12 bolt and no 4P on the cowl tag?  The car in question does not have the original engine or transmission and has a 3.08 open 10 bolt rear.  The car also has a 3/8" fuel line.  It does have the 2LG on the cowl tag and is a V8 car.  I do not remember the vin or all of the cowl tag but will get it to post.  The car has never been restored and I personally know the owners of the car back to 1971.

Thanks in advance,
Russ

Sure sounds like a LF7/M20 car.
No, no known exceptions.
