Palm trees in NJ? High dollar Florida dealer has been turning down offers on it for a while. https://www.ebay.com/itm/Buick-Rivera-16k-Original-Miles-Simply-Stunning/392134593058?hash=item5b4d0b0a22:g:-fcAAOSwC0dbso-t&vxp=mtr

I see the 68 430 was 10.5 compression, do these cars adequately cool on 93 octane? I've had to enlarge combustion chambers on a Pontiac to stop spark knock and overheating, but that was on an earlier car with a vertical flow radiator. Thanks
