What kind of gas do you run at the track ?

I would try mixing a liter of Boost additive first.My friend uses it with his 422c.i W2 headed pump gas stroker.Runs 10.62@125mph in a 69 Dart.Worth a try and cheaper.:D

I tried octane boost , absolutely worthless , at least the junk I tried . You know of a good product I could try .
