High rpm's maybe, but not a little boost. I assume it's already a big heavy strong iron block ?

And what are the heads made from ? Surely nearly all American engines will be fine for unleaded ?

Certainly at less than £1k, yea go for it. it would be a waste of money to do stroker and turbos though, and a stroker will place more load on the main caps than a bit of boost.

But dont forget to budget in for proper fuel and ignition control. Although a carb/dizzy could be made to work to a degree as well. No idea what you're using at present ?

Even if you had to stick to a carb, I'd still go for mapped ignition with boost. And fix that oil pressure, it's far too high.
