What was the compression ratio of a 1982 V8?
If you looked over the spec sheet for the 1982 5.7 liter Cross-Fire V8, this motor appeared to be a very high-performance V8 – it had a 9.0:1 compression ratio. The previous year’s L81 only had a compression ratio of 8.2:1.
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 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.
Do you need a torque wrench for a 318 Mopar engine?
When you’re rebuilding a 318 or 360 Mopar engine, you need to have a torque wrench that can do both light and heavy torque settings. When torqueing the intake manifold on these engines, you need to two-step the torque, following the bolt pattern in the image above, to a maximum of 35 lb-ft.
What are the torque specs for a boss 351C?
If you use after-market performance bolts like ARP’s, you should follow the recommended torque specifications. 351W Torque Spec. 351C, 351M Torque Spec. 40-45 ft-lbs. (45-50 ft-lbs. For Boss 351C) 105 ft-lbs. (125 ft-lbs. For Boss 351C)
