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).
How to tighten the main bearing cap bolts?
Tighten the main bearing and connecting rod bearing bolts. Tighten the main bearing bolts in two stages. Stage 1: 25 Nm. Stage 2: 60 degrees. Tighten the connecting rod bearing bolts in two stages. Stage 1: 35 Nm. Stage 2: 90 degrees.
What should intake manifold bolts be torqued to?
Intake manifold bolts on SBC engines should be torqued to 30 lb-ft in a two-step sequence. 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.
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.
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 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.

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 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.
How much torque does a B series head nut have?
“ARP HEAD BOLTS”ALL B-SERIES lube top nut threads only with 10w30 or ARP Molly lube then use 5/16 allen key to torque bolts to 10ft lbs into the block> Torque in steps: 30ft-lbs (360in-lbs),60ft-lbs>> (720in-lbs) Then to 80ft-lbs (960in-lbs)
What should the torque be on a 302 engine?
If you’re putting together either a 289 or a 351, the rod bearing caps on these engines should be torqued to between 40 and 45 lb-ft. On the other hand, you’re going to need to be careful with the rod caps on the 302 engine as they are only supposed to be torqued to between 19 and 24 lb-ft.
Do you use torque specs for ARP bolts?
DO NOT use torque specs for off-the-shelf ARP bolts. Here is a diagram of some important bolt identifying features. The following chart shows the head of the bolt, the dimensions, and the proper torque spec. Be careful! the heads of some bolts look similar and some even have the same markings. DO NOT identify the bolt by the head alone.
How to determine the torque of a connecting rod?
STEP 1: Your Crower connecting rods came with a connecting rod specification tag. Check the tag to find the rod bolt part number used to fasten your connecting rods. Rod bolt length listed here is the measurement from under the head to the end. STEP 2: Use the chart below to determine the recommended lubricant, rod bolt stretch and torque amounts.
Do you have to torque your rod bolts?
Torqueing your rod bolts without pre-determining the required torque to achieve the correct rod bolt stretch is not recommended. However if this is the only tightening method available to you, DO NOT EXCEED THE TORQUE AMOUNT INDICATED FOR YOUR BOLTS. NOTE: Your Crowerods are totally rebuildable.
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.
