Everyone has there own Idea as to what is streetable and what isn't. Yes a 12-1 is not streetable to everyone. My and I say MY
250 was pushing over 12-1 as a daily driver 583/607 lift cam. It ran on 87 L cheap O gas it ran upper(high) 14s LOW 15s with 3:08 gears and 16mpg city. It would start with a Bump of the key. ANd NO this motor did not ping a lick.BUT it would not shut down with out loading the clutch OR useing 112 in it.But anyway I ran That motor for over 17 plus yr. And Reused the same Pistons in a new Build.
But anyway bottom line is either Pay the fuel bill Or drop the compression.
