1.25 or so HP/C.I. from a 390

It's fairly easy to do. As BJR says, he's doing it with smaller inches and rpm. IMO, the stroker will do it with less inches and rpm. In any event, it's not that hard. You will need good heads, and the cam will negate power brakes, but otherwise it's easy.

I'm thinking the same thing, should be easily within reach. Just wanted to confirm that the architecture will support this type of output without a lot of speciall considerations.
