Ready to put my 261 together can someone supply me with all the Torque numbers I will need. What I really need is a manual for this engine. Can't find one. If someone will scan and e-mail a part of the manual that would be great. My engine is out of a 1959 (Canadian) Pontiac car. Does anyone know were I can pick up a manual ??? Thanks.......
