Re: Gas confusion

Some Conoco stations here in the PNW have 91 Octane non ethanol and that is what I run in my boat and my small engines. I'll run it in my 71 with the 500 Cad when it hits the road too. The engine will need premium with the early heads.

My ongoing truck projects:
48 Chev 3100 that will run a 292 Six.
71 GMC 2500 that is getting a Cad 500 transplant.
77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
