No street or track.
Well if you can’t drive on the street or the track then how’s about two rails close to the street?
This must be the one and only Pontiac like this I would guess.

OK, but what's the proper cam choice for this application?

The name hi-rail comes from the shortening of highway and railway.
Maybe powered by the 316.6 cubic inch "Strato-Streak" V8 engine. You can bet the retractable street tires sure wouldn't need much torque to do a burnout on steel rails  .

I have seen remnants of a '57 in an AZ Salvage yard.
Got photos around here someplace...

I'll bet it handles like it's on rails.

If it ran on 3 rail track like O gauge Lionel does would it be fitting to have a Tripower motor in it?

A FWIW.... the Thumpr cams have their roots based on road race track use where the cars benefitted on power coming off the corners.
"Believe it or not, the Comp Cams thumper grinds run very well, and sound real good too. I have used them many times, and the performance is much better than expected, and they have the DRIVE IN IDLE sound that people want." JOE SHERMAN RACING ENGINES Cams are like people's personalities, what works for one won't necessarily work for others. If you do a search here on the Thumper subject you will find a lot of negative opinions and comments, like XE flat tappet cams ! .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
