Since (with the help of others) I have determined I have a 261, I need to find some info on this engine. On the 6066 gmc webpage it has info for all inlines but this one. I would like to fond out torque and hp ratings to see if this is the engine I want. Does this engine compare to the 292?? Does it have the low end torque and is there room for improvement?

Also the book: Chevrolet Inline Six Cylinder Power Manual has been highly recommended but it doesn't look like it covers 261's. Does anyone have input on this??

Thanks
