main cap tightening sequence?
Start in the middle alternate left and right out to the ends. Slightly rocking the crank after each main to make sure no tight spots as you go.
My particular approach is to bring them up to 30 ft lbs each, then bring them up to 60 ft lbs each, then to 85 ft lbs each to finish them off (small block).
Think of it as stretching the block as you are tightening them up. Want to tighten them up evenly as you go so you are not pulling things out of shape.
Want to maintain an even centerline on all crankshaft main journals.
