Very lucky you didn't have a JHoffy moment and scatter the thing.

 

Anyone run a higher octane fuel in their 351?

 

I've paid some attention to this over time as I didn't want to get a 351 that NEEDED high octane. I ride into desolate areas and need to fill with the only station around, which may be 87 or sometimes only 85. Some other riders do, but I think most don't use high octane, and I don't recall many (or any?) announcing detonation issues with low octane fuel.

That said, I'm running 91 ethanol-free for my first tank and hoping to get to the dirt this weekend for more fun and fumes.

 

Unless you did something to run it real lean, or, to bump up the compression ratio, I bet you'll be fine with 87.

 

With the big bore I tried running a skosh of race gas just to see if it helped. But it seemed to run better with premium fuel. Not so with the huskys......

 

yes 12/1

 

Yes, but lets leave JHoffy out of this. You may summon him by mentioning his name.

 

I noticed that the shims have worn or were not very accurately manufactured. I measured with a fairly decent micrometer the intake shims were 3.08 each and the exhausts were 3.03 and 2.99 or am I being somewhat retentive here.

 

A true micrometer or a vernier caliper? If a micrometer, what kind?

 

It was a starrett vernier caliper I think a 799a was the model number
