Tighten the bolts on the second pass in sequence 1-8 to 12 N·m 106 lb in. Use Loc-tite blue on these bolts and follow the above sequence and torque levels.
It's generally a circular pattern that starts in the center and works it's way out to the edges. The dual overhead cam L31 had a front longitudinal design, two valves per cylinder and required a four bolt intake manifold. What is the angle between the two holes and can I remachine and spot face new holes. Bolt - Rod Cap Type: Dim: Length: Head: Grade: Crankshaft To Engine Block 75 Ft-Lbs 900 In-Lbs 101.

You want the gas to remain suspended in the air all the way to the intake port. It had a displacement -- the amount of air and fuel exited from an engine during a full cycle --of 5,735 cubic centimeters, and compression ratio -- the maximum engine volume compared to the minimum -- of 9. The Aluminum intake manifold on a 98 Vortec 350 engine should have 8 bolts total, located in the 4 corners…. Form Haynes Repair Manual 36071 4. I don't know how to post a drawing, but you should torque an intake in three stages starting with the four center bolts and then going down to each of the four corners.
I started installing a Edelbrock Pro-Flo Fuel Injection system and can't get the two center bolts started due to the center theaded holes on the heads being at different angles. In 1966 the inline 6 cylinder engines included the 230, 250, and 292. I just had to tear mine down due to a blown intake manifold gasket on the water port located above 1 Piston.
