Possible switch from alcohol to gas... looking for opinions.
Have a 390 with 13* heads right at 16:1 compression ratio. Turns 8-8700 regularly.
What kind of fuel suggestions does anyone have?
Looking for suggestions on octane #s and brands and blends people have had success with. LM+ or C16 was my first inclination but not sure if LM+ has enough juice to not detonate.
