Fuel Type

[e3g6l3]

What type of fuel should I be using for my 1970 Lt1?
I have already had some confusing views, and am looking to get a little more confused.

As high of an octaine as you can find That is a very high compression engine which needs the octaine. If it pings you need higher octaine or need to retard the timing until the pinging goes away.
