I installed a 64 413 in my 69 Super Bee that I had and I ran it hard and never had a problem.  I put atf in the fuel tank once in awhile.

Both trips are a combination of in town and freeway driving. The top speed is around 75 mph for short periods.

That way, you will know that unleaded fuel is okay for your car.

I have only heard of a few actual cases of it, but I think it is a very real issue with extended high speed driving of older engines on modern fuels.
