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,
