At this low an rpm you would need forced induction or nitrous, but still entirely possible.

Build a basic 350 with a Comp Nitrous HP can and forged pistons, and NUKE IT... a 300 hit is very doable! You do want headers and a BIG exhaust sys if running nitrous, do the large quantity of exhaust gas generated by the N20

Yes its very possible, the previous owner of Radir wheels is a friend of mine that lives close by and he has a '32 vicky with a 350/350 combo and he runs the nostalgia drag class with over 800hp and can still wipe the floor in a show. Hes done a multitude of work to it, from angle plug heads to the tiniest details.

Katech makes naturally aspirated 310 cid mills that put out over 600 HP. However, they are turning 8,000.

Nitrous is definately your best bet in the RPM range you are looking for. Like JdOwNj said, use a nitrous cam. These cams use an earlier opening on the exhaust valve to release some of the extra exhaust created by the induction of nitrous. If you don't do this, you lose power to "pumping" losses, the resistance to flow through the exhaust valve.

These type of cams are supposed to increase the utput of your nitous kit by 20-30 percent

Use a single plane manifold with nitrous nozles in the ports.

Use efficient cylinder heads, like the AFR's and run the biggest valves you can.

Have the block bored and honed with torque plates for a good ring seal. It would be cool if you could use Total Seal gapless type rings, but I don't know anyone who had run these with nitrous...maybe someone here does?

I run em wit nitrous, they run ok, I do run a fair amount of piston to wall clearance though... It will be interesting to see what they do as far as ridge wear... Id be pretty careful useing them... but I have a dyno sheet that says that they saved me 45 horse under a 150 horse hit...
