Urm what is your Idea of streetable?
A P/P Na 13b if set up correctly can make upto 300bhp (Flywheel).
They can be made more tame but you cant expect to build an engine with the most Radical style of Porting and it to behave in Trafic.

Ken Scheepers 13b n/a pport makes 335'ish to the wheel but would not be at all streetable with it's current setup. It is fuel injected alcohol. Best time 10.25 which is an NHRA Import record.
I would be more inclined to turbo a pport setup for a street setup and shift the intake timing up a little higher and play with a number of removeable chokes to try to gain a bit of low end torque to help the streetability but find a optimal balance to keep pulling solidly through the higher RPM range.
I don't think anybody has really worked them from that type of angle (chokes) and spent the dyno time for what I am suggesting. After all it would be pretty time consuming which equates to $$$ consuming

look at those airplanes that have rotarys and a PP, they make some good hp at a low rpm. 215hp @6000rpm...
if you where going to do this on the street, i think it would be a little lower since you are going to have more restrictive exhaust system.

thats some nice lowend power on this baby. looks like it could be streetable.

thats a LONG intake manifold!
remember, long runners = more torque, short = high rpm power, just like an exhaust manifold.

You could make some modications to change it but I think chokes would give you a way to change it on the fly.
