What size engine?
My wife and I had a ‘67 Olds 98 w/a 425 unites high compression engine. IIRC, it was an 11-1 engine. It was a beast and very comfy.

330 cubes 320 hp might have been 11.2 to 1 i liked the ultra hi compression on the air cleaner
the 800 carb was very loud when punched at 40 mph in 1st lol
edit
online it says 10.25 to 1
it was higher then that said premium gas or super only as well
