Thanks all for the replies.
I work for an airport. but have never ckd into the availability to buy AV gas . Sounds like I may need to .

I have a drag strip less than maybe 5 miles from the house and might ck there to see if they can pump race gas on site. Otherwise Ive found a location that sells it maybe 10 miles away.

At some point in the next few years I will be looking at opening this thing up and do a piston swap to drop it a pump gas friendly level

Ive not heard to much good things about octane in a can over the years and wanted some 1st hand information
