There a bit of info on the 377 Scorpion on OSO. Just type 377 Scorpion in at google.com, you'll get tons of info.
I don't know your specific application...but in general, it's hard to screw up an SBC. Best I can figure, it's a 4.00" bore and 3.75" stroke - which is basically a "383 stroker", without the .030 over bore.
