1994 chevy 350 which is cylinder number one - 1989 Chevrolet C1500

It is possible to upgrade a 1987 Chevy 350 engine to a serpentine belt assembly using parts from a 1994 Chevy small block engine. However, there are some differences between the two engines that may affect compatibility.
One major difference between the two engines is the placement of the alternator. On the 1987 engine, the alternator is typically mounted on the driver's side of the engine. On the 1994 engine, the alternator is typically mounted on the passenger's side of the engine. This means that the brackets and pulleys for the serpentine belt assembly may be different between the two engines.
Another factor to consider is the number of pulleys on the serpentine belt assembly. Some 1994 small block engines were equipped with additional accessories, such as air conditioning or power steering, that require extra pulleys. If your 1987 engine does not have these accessories, you may need to modify the serpentine belt assembly to remove the extra pulleys.
To ensure that the serpentine belt assembly from the 1994 engine will fit your 1987 engine, it is recommended that you compare the parts and brackets from both engines side by side to identify any differences.

Is the timing set to # 1 cylinder tdc or is 180 degrees out. Remove valve cover and bring cylinder 1 to tdc both valves will be closed, ensure distributor is set to number 1 firing.

This 4.3 V6 is just a 350 V8 with 2 cylinders missing and even a V8 trans will fit/interchange physically being the same bolt pattern and size. If it's the same shift pattern and both transmissions are overdrive transmissions, yes, it will interchange. If it's GM, it'll swap. From 1988 the automatic transmissions have a multi bolt pattern and Pontiac, Caddy, Olds and Chevy, all will bolt up.

dont go by that..do this.. bring the 1 cylinder to top dead center by matching the timing marks on the engine..then take off the cap.. look at where the rotor is facing..thats your 1 plug spot..then the rest follow one at a time all around the top of the cap..1-8-4-3-6-5-7-2..

well number cylinder is the drivers side front cylinder, follow the wire to that cylinder

The number one cylinder.It is the front plug on the drivers side.Good luck.

Hope this help. (remember rated this post).

Check for leakage from the intake manifold gasket where it mates with the cylinder head. Very common problem.

As far as fitting in the truck, no problem. Yes you will need a new computer. Your best bet would be to find a salvage truck with a 350, get the engine & the computer from the same vehicle. Most of the sensors are the same although, best case scenario is to get a complete assembly out of a salvage vehicle, including all the sensors. Motor mounts are slightly different, but you can pick those up at a parts store.

If you use a motor with a carb, you won't be able to hook up all the necessary sensors and this will cause your Check Engine light to come on at the very least, and possibly interfere with some or all of your gauges. (Remember, everything is tied together...including the gauges)

Hope this helps.

firing order for a chevy k1500 series 350 is 1,8,4,3,6,5,7,2 with number one cylinder being left front side of the engine
