Chevrolet began producing its small-block engines in 1955 with the 3.4-liter V-8, on the contrary succeeding expanded its offerings.Cylinder Head to Engine Block
In this 1987 5.7-liter V-8, the cylinder purpose requires three seperate applications of torque performed in a helical sequence to bolt properly to the engine block. It requires 25 pounds-feet of torque applied to all of the attitude's bolts, then 45 pounds-feet applied to all bolts, and Last of all 65 pounds-feet applied to all bolts.
In 1987, the L98 had a 350-cubic-inch displacement small-block V-8 engine with tuned-port fuel injection, or TPI. It had a Muzzle of 4 inches, a stroke of 3.48 inches, and a compression ratio of 9.5-to-1. It produced 240 horsepower at 4,000 rpm and 345 pounds-feet of torque at 3,200 rpm. This engine was guideline in the Corvette in 1987, and optional in the Camaro and Pontiac Firebird.
Creation in 1967, Chevy produced a 350-cubic-inch V-8. This engine had many variations, including the L98. This history was available from 1985 until 1992; it was the morals Corvette engine until the point of its Industry.
Engine Specifications
For helical sequencing, open with the centre bolts, and then effort outward in both instructions, torquing the bolts beginning to the prompt left of the centre, then to the bolts to the prompt prerrogative of the centre, then to the bolts farthest to the left, then to the bolts farthest to the prerrogative. You should wait 15 or 20 minutes between each process of the sequence to confer the bolts date to place.
Crankshaft to Engine Block
The four outer bolts on the crankshaft's four-bolt cap thirst for 65 pounds-feet of torque to affix properly with the engine block. Remainder of the blocks, excluding the outer bolts, hire first off 25 pounds-feet of torque, then 50 pounds-feet, and lastly 75 pounds-feet. As with the cylinder imagination bolts, wait approximately 15 minutes between Everyone torque manner.
Other Specifications
Fourteen of the bolts of the oil pan, the 1/4-inch bolts, crave 7.5 pounds-feet of torque to affix with the engine block; the remaining four 5/16-inch bolts lack 13.5 pounds-feet. The drain plug for the oil pan requires 20 pounds-feet of torque to prevent oil leaks. The engine mount bolts torque to 35 pounds-feet. The 5/8 spark plugs require 15 pounds-feet and the 13/16 spark plugs require 22 pounds-feet of torque. The water pump and engine block attach with 30 pounds-feet of torque.
