I was fairly dead set on running 87 octane as its obviously the cheapest and gas in Canada is ridiculous. 91 is premium and is usually 20¢ more a litre. Today premium is $1.33 a litre ($5.32 gal). That would make 87 about $4.52 a gallon. I feel like a cheapskate evening talking about it but an extra $1.20 a gallon for pump gas will add up. On the bright side, I found a local supplier of methanol at $5 a litre. May end up being cheaper to inject a 50/50 of that.

Long story short, I'm glad you caught my low compression idea as with your info, and several articles online I'm convinced 9:1 or even a little over is ideal for me. The alc injection, intercooler and cam shown above should be safe enough and still "easy" to tune at 9:1.

Goals: Near daily driver in city/rural/small island roads, stock gears (2.73s?), th350 with shift kit, 67 Camaro (approx 2900 lbs).
