Is there a order in which you tighten crank caps on 350 chevy?

Yes, there's a recommended tightening sequence for the crankcase caps on a 350 Chevy small-block engine. It's generally a criss-cross pattern to ensure even clamping force and prevent distortion of the block.

While specific torque specs are crucial (and will vary slightly depending on the year and specific application), the sequence is almost always some variation of:

1. Start with a cap at the rear main bearing.

2. Then go diagonally opposite.

3. Continue criss-crossing until all are snug.

You would then tighten them to the specified torque in that same criss-cross pattern. Always refer to a shop manual specific to your engine's year and specifications for the exact torque values. Using the wrong torque can lead to damage.

Don't rely on just this general sequence. Find a reputable service manual or a rebuild guide for your specific 350 Chevy engine. This will give you the proper torque specs and the precise tightening sequence.
