Which is near enough to 280 cubes IMHO.

I have a motor that I have done this to. It is currently pulled down for inspection, and I will post pics of the internals if you guys want them. Oh, BTW, Rods are datsun, pistons are Holden.

Check here if you feel the need.

Well I have strugled keeping my Bored/Stroked Stage 4 Cross Flow
together for the last 3 years (been costly, would not recomend it)
however I finaly have it sorted!!!!!
To start, its now stroked to 280, and it consists of an aray of strong parts (I say this cau's I do like to give it a hard time, love to be sideways) here we go:
Hardend crank, performance harmonic ballancer (good for 8000rpm) nissian rods, high tensile bolts, 60thou over toyota pistions,
10:1 compression, Stage 4 CamTec cam, ported & polished head oversize inlet & exhaust valves, heavy duty springs to suit cam. Still running slightly modified (but STOCK) rods & rockers. Induction is currently a redline manifold with a 4 barrel 460 holly bolted to it. A set of pace maker extractors & a 2 & a half inch free flowing exhaust, and last of all
a PRO COMP dizzy & ignition with a standard 12v coil. (revs like thers no tomorow)
Injection, Roller rockers, and a turbo are part of a new project. :
