A mild, modern cam and an ignition recurve would wake it up for not a lot of money.
No squeeze.
compression ratio is 8:1 on this engine.
That's the mild, modern cam part. Something like the mildest Lunati Voodoo for example. The lobe designs available now will increase cylinder pressure and improve torque and response over the lazy lobes of the stock design. More power, response, and mileage. Getting some ignition timing in at lower rpms will accentuate the effect.
