Is E85 an option for you? That way you could bring the compression up, which can also allow you to run a more aggressive cam. An aftermarket block would be much better but you already know that. And B1 original heads would get you there easily.
I wish. Three stations that were supposed to carry it don't. I'd rather run pump gas if possible but open to 50/50 mix race/pump. Not really a street car. Maybe once in a while for certain occasions.
