What the best gasoline mix to use?

[FWB]

if i was at say 10:1 the head gasket approach would be fine. at 11:1 to get down to say 9:1 the gasket would be so thick to change the cc of the head
that my rocker geometry would be binding. the cr is not the only factor in gas
requirement. cly head flow, camshaft, and stroke play a significant role in this also. the limited driving i do with the car wouldn't make me change the build
so i don't have to add a half quart of lead. remembering to keep the quarts in the trunk is the hard part.

Ya know, sometimes it gets pretty hot in the trunk when you park it out in the sun. You might want to be careful storing combustibles like that in your trunk. We had a thread on here not too long ago about cans of "Fix-a-Flat" exploding in trunks....

Good point, sounds like this is an ideal time for me to see how hot a quart can
get before she pops.

Note: my wifes name is not quart

Cool. Please take a video while you're doing it.

Thanks for the info.
Car does not currently ping, but I've never run it on just 93 octane. Didn't even think to try. I'm not sure what my octane is in the tank. I just go into the store, buy a bunch of octane stuff and pour it in. My friend who works on it, in exchange for defying the grim reaper between my town and his, comes and biopsies my wallet and puts 10+ gals of race gas in it at a time. I call whatever is in there "gas gumbo". If high price = high octane, than I'm running a solid fuel booster. Problem is, the place where he gets it is other side of the county, and I live not too far from the airport. Anybody got a problem with aviation gas? He says, "don't do it"......? As far as all the technical stuff, I opened a pandora's box, because, unfortunately, I wouldn't know a cam shaft from a colonoscopy. I wish I did, though.
