I have a 1980 351 windsor ProAm. What is the best gas to put in it to get the best performance and milage out of it?

Different motors seem to break in differently. My old boat would actually run like crap on premium. The new boat I don't see a difference.

I would just try a tank of each. If it runs fine on regular, just use that. Usually the price difference eliminates any savings on fuel. You might use less, but it still costs more.

A lot of times on the lake you may not have a choice anyway.

I have the same engine in my MC and it runs fine on regular. I did run premium for a few years and saw no difference.

Or you can run what ever you are able to siphon out of your neighbors car.

I would start by making sure your timing and points are set correctly and that your advance weights/springs are in good shape. Nothing will make it run better if your timing is retarded.
