On most 350's, put both sprockets on then turn them so that the dot on the crank sprocket is straight up and the dot on the cam sprocket is straight down. Remove the cam sprocket, put the chain around it and slip the chain around the crank sprocket while placing the cam sprocket back into position, being careful to maintain the orientation. There were a few years around the late 70's where both dots are straight up. You would know right away when you adjust the valves because you would be assuming #1 was up for compression, and one of the rockers would be down to push the exhaust valve open. Rotate the crankshaft one revolution and readjust the valves.

There will be a mark on both the crank gear and cam gear, these must point directly at each other (the marked teeth will mesh). On plastic cam gears, there are several marks; care must be taken to distinguish the correct timing mark from stray plastic casting marks.

What should the timing be set at after you have replaced the timing chain on a 1994 Chevy s10 2.2 liter engine?

Put the crank shaft at TDC. There is a dot on one of the crank gear teeth. It should be pointing toward the cam gear. Put the cam gear on without the chain. Turn the cam until the hole in the cam gear is pointing toward the crank. In other words, the hole in the cam gear and the dot on the crank gear should be in line. Then simply remove cam gear and apply the chain. The computer does the fine timing. Nothing to adjust.

How does an engine works and the function of a gearbox?

An engine is a device that converts chemical energy in the fuel to mechanical and heat energy. This mechanical energy is used to drive a crank shaft which is used to power the wheels of an automobile. The crack shaft is connected to a gear-box which changes the speed and torque of the drive shaft. A lower gear (low speed and high torque) is used for acceleration from halt and a higher gear (high speed and low torque) is used for cruising.

It is usually found closes to the bottom of the engine at the front, just follow the belts to the bottom.
