Dear Mr. Debane;
The 261 built to 278 CID can make as much as 250 horsepower (normaly aspirated) on 'pump gas' and will rev to 5,500 RPM (safely). More can be had with fuel, NOS or using a turbo etc.
This engine built to 285" (Cadillac 6) or to 292" using the same "stroker" crank is limited to 5,000 however. This 'high torque' version is best used in vehicles (over 3,000#) for "street" use. This one is a great item for cars of the 40s & 50s as It's twice the Hp/torque of the 'stock' 85Hp 216 engine and bolts right in.
I don't believe there are any actual torque figures availabe, but you could check with Tom Langton to be sure.
I'm told he has a 'short block' for around $1,800.
Good luck.
