Detailed Torque Specifications

When you’re working on your Ford 390 engine, it’s very important to follow the specific tightening instructions for each part. This is because each part needs to be tightened to a specific level to make sure it works properly and lasts a long time.

Here are some specific instructions you should know:

  • The main cap bolts need to be tightened to somewhere between 95-110 foot-pounds.
  • The connecting rod bolts should be tightened to between 50-73 foot-pounds.
  • The cylinder head bolts need to be tightened to 65-75 foot-pounds.
  • Other parts also have their own specific tightening levels.

Setting Timing for Ford 390

Tweaking the timing on your Ford 390 engine is crucial for making sure it runs smoothly and at its best. First, park your car on flat ground and set the parking brake for safety.
