Does anyone know if chevy ever made a factory stock chevy 350 engine with a compression ratio greater than 9:1? (Using standard bore and stroke). Also does anyone know a math formula for computing compression?

yes, im pretty sure they did, they had 350's in 69' before all of that emissions crap.

I will get you the compression formula soon...
