Are motor mounts good? You'll definitely hear it when the engine torques up and then bang back down.

I have a 94' Chevy blazer 4x4, 4.3 L Vortec. It started knocking out of the blue.

No this is a bullet proof engine, but things like this do happen from time to time.

I have a vortec out of my 1995 chevy silverado will it work in a 1998 blazer with a vortec? I believe they are both 4.3L but i could be wrong...and the blazer is 4x4 will that affect the swap

If there both 4.3's the interchange says the will fit but I have found that you need to look everything over well. I have found that some have knock sensors with different sizes (2 wire and 1 wire) and the oil pan and pump sometimes have to be swapped going from 2wd to a 4wd. Sit them side by side and check everything is my best advice.

Know if my 95 chevy blazer has a spider CPI?

A spider injector is located underneath the intake plenum and this is multi-port. Otherwise you have a throttle body injector system. Vortec engines have spider injectors and they are super expensive to replace ($400.00- 850.00) each ! There is only one spider injector for each engine it has 6 legs/fuel tubes that go to each cylinder.
