What should main bearing caps be torqued to?

Main bearing caps on 318 engines should be torqued to between 85 and 90 lb-ft., while 360 engines should be torqued to 85. The books also specify two different types (strengths) of main bearing cap bolts. They also specify a two-step torque procedure again, as well as a specific pattern to use (Image above).

What are the torque specs for stock bolts?

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP’s, you should follow the recommended torque specifications.

What are the torque specs for a Gen 3 iron block?

What are the torque specs for a Ford engine?

As for the torque specifications, the 289 (above top) and 302 intakes are both torqued in two stages to between 20 and22 lb-ft. The 351 intake, on the other hand is torqued in three stages to between 23 and 25 lb-ft. Ford Head Bolt Torque Sentences and Specs The torque sequence for all three Ford engines can be seen in the photo above.

What are the torque specifications for an engine?

Torque specifications are for stock factory type bolts with light engine oil applied to the threads and the underside of the bolt head. Other lubrications offer reduced friction and increased bolt tension, and will affect the torque figure.

What should the torque be on a 327 engine?

SBC Crank Main Caps and Rod Bolts Main bearing caps on 327 engines should be torque in two steps to between 60 and 70 lb-ft, while 350 engines should be taken to 75. These are the caps on the crankshaft. Rod caps, or rod bearing caps, should be torqued to 45 lb-ft for the 327 engine and 35 for the 350 engine.

What kind of torque does a Windsor engine have?

With dowel pins (Windsor engines), all you have to do is tap them in place before installing cross bolts. Torque Romeo jackscrews to 4 ft-lbs, and then 7 ft-lbs. Torque cross bolts to 14 to 17 ft-lbs. Torque Windsor cross bolts to 20 to 24 ft-lbs, and then 85 to 95 degrees with a torque-angle gauge.

What should the torque be on a 351 engine?

The main bearings on the 351 engine are torqued to between 95 and 105 lb-ft-you’re going to need a good angle as well as a good grip on the torque wrench to hit that accurately. It should also be done in three steps. The other two engines aren’t as beefy, so they only get torqued to between 60 and 70, with two steps.

What’s the torque pattern for a SBC engine?

First time around, set your torque wrench to 20, follow the pattern, then repeat the pattern (image above) again after setting the wrench to 30. The image above shows the torque pattern to be used when reinstalling the heads on any SBC engine. “The book” says to follow the pattern twice, cutting the torque spec in half the first time.

What are the torque specs for SBC engines?

Intake manifold bolts and head studs/bolts have to be torqued in a certain pattern and to a certain torque spec in order for your engine to work properly. Intake manifold bolts on SBC engines should be torqued to 30 lb-ft in a two-step sequence.

What should the torque be on a 316 engine?

When rebuilding the 316 engine rod bolt-rod bearing cap torque should be set to between 45 and 50 lb-ft., This differs from 360 rod bolts that max out at 45. These should be done in two steps, doing both bolts/nuts to approximately 20 lb-ft first and then doing both to the final torque.
