Yes it will fit but here's the problem.
The transmission in the 94 is computer / electronic controlled and it must have all the engine sensors that the 94 engine has to shift right. You would also have to install a fuel pressure regulator to lower the fuel pressure.
The 86 engine is NOT a computer controlled engine.
You need to install a 1988 through 1995 engine in that truck so you won't have any problems. Then you will be done with it.
Yes it will.
Yes it will,
'86-'88
376 c.i.
its an 86 chevy silverado
i believe it is up to 86 maybe 88 that are the same truck.
Yes, That is a direct bolt on and the body lines will match right up.
Chevy car rally wheels....yes. Truck....no. Except S-10.
assuming the automatic was the same or near in year yes if you only swap the engines
YES. The 74 and 86 engine blocks are the same as far as DESIGN.
The heater blower motor is under the hood bolted to the heater plenum on the passenger side of the car.
All fuses are under the dash on the driver side.
