no... the 4.3 l engine is a v6 and the computer controls the ignition and fuel injectors for only 6 cylinders, dropping in a v8 adds two more cylinders, what you need is (depending on the car ) the computer from the same model but one that had a 350 in it to begin with... a good place to look for one is at a junk yard The computer out of a 4.3 will work if it is a 93 or prior computer with a throttle body, and the 350 going in is also a throttle body. It's almost just a plug and play swap

### What is the LCM of 34 43?

To work out the LCM of numbers you first need to split them into
their prime factors. In this case:
34=2x17
43=43
The next step would be to identify any common factors, but as
there are none, we simply take the factors we have and work out the
product:
2x17x43 = 1,462
So the LCM of 34 and 43 is 1,462

The engine runs good. Under load and accelaration, the car loses
some power and service engine soon light comes on. Normal driving
