Chevy 350 Head Bolt Torque Specs
When working on the Chevy 350 engine, it is crucial to follow the correct torque specifications for the head bolts. Proper torque ensures that the head bolts are tightened to the appropriate level, preventing leaks and ensuring the engine’s optimal performance. Here are the recommended head bolt torque specifications for a 94 Chevy 350 engine:
| Step | Torque Specification (ft. lbs.) | Torque Specification (Nm) |
|---|---|---|
| Step 1 | 25 | 34 |
| Step 2 | 45 | 61 |
| Step 3 | 65 | 88 |
Procedure for Torquing Head Bolts
To ensure the proper torque of the head bolts on a 94 Chevy 350 engine, follow these steps:
1. Start by cleaning the threads of the head bolts and the bolt holes in the engine block to remove any dirt or debris.
2. Apply a small amount of engine oil to the threads of each head bolt.
3. Begin tightening the head bolts in the specified sequence, starting from the center and working your way outwards in a crisscross pattern.
4. Use a torque wrench to tighten the bolts to the specified torque for each step. Be sure to follow the sequence and torque specifications mentioned in the table above.
5. Once all the head bolts have been torqued to the final specification, double-check each bolt to ensure they are tightened correctly.
6. It is recommended to recheck the torque after the engine has gone through a heat cycle, as the expansion and contraction of the metal can affect the torque.
Following these torque specifications and steps will help ensure a proper and secure installation of the cylinder heads on a 94 Chevy 350 engine. This will contribute to the engine’s longevity and performance.
Remember, it is essential to refer to the specific torque specifications for your engine model and year, as they may vary. Always consult the manufacturer’s guidelines or a reliable source for accurate information when working on your Chevy 350 engine.
