Make sure the dome piston will work with those small chamber heads.

The smaller the dome and the more you mill the head the better she'll run. Saw this combo before at around 13.8:1. Runs good.

a hydraulic cam kills any advantage of that combination...

You'll want to run a 327 piston. A 350 piston would be way off with that crank (like .125" down in the hole with 6" rods).

A hydro cam isn't a deathtoll, but cam, spring and lifter choice is more critical. Lunati has a few cams with 245, 246 and 255 @.050" durations and Camcraft could make you one with anywhere from 242 and up. You'll need at least 240 duration @.050" to get up around 6500 rpm.

I'd get 6.125" rods and use 350 pistons. Longer the rod (read:lighter piston) the better.

And chainsaw is about it too.
