Pulling some parts off. You can see the Buick the engine came from that was donated to the school. 

3.8 installed and body primed white

Removing intake

When we went to bolt the supercharger on we discovered why everything said we needed to replace the heads. There were no holes in the heads for the injectors. The (N/A) natural aspirated engine had holes in the intake. The supercharged engine had them in the heads. We had to go to the junk yard and get heads.

Now where do we install the injectors :0

Got to keep everything clean good job John

Trying different options

Off to the track

Our best time at the track so far was 8.44 but the speeds were really slow. At the end of the track it was not shifting into 3rd. It was running the rev limiter a lot. We brought into class to do a shift kit.

 

We had to remove the side cover to remove the valve body

The frame and everything came out

Here is the valve body with new gasket we ground some valves replaced springs plugged some holes and drilled bigger holes in the plate. We even had to drill the case.

 

When removing the Accumulator’s we found broken springs. we are installing new pistons and seals as well. 

 

 

We dug a little deeper after that

 

 

We also took a look inside the transmission and we found 2nd gear clutch pack fried

 

Pretty much any forward clutch was fried.

We gutted the entire unit

 

Rebuild kit arrived time to install some parts
