8:71 Supercharger install on 454ci powered '55 Chevy
You would think a supercharger kit install would be pretty simple .... well no, is the short answer.
A wise man once told me a 'kit' is not a solution. And having worked on a few of these set ups now these words keep ringing in my head and I remember this old man who at the time I didn't think was that wise at all .... now I am older and I see.
In this install I had to port match the heads to the intake as there was a substantial lip into the head port because of the large intake manifold ports. If not corrected would have led to fuel puddling and fouled plugs and drivability problems that would have been hard to diagnose once assembled. Also the distributor hole at the back of the manifold was off centre and way too big for a standard chevy dizzy and any aftermarket dizzy too. So I had to make a boss to take up the slack and provide a stable boss for the dizzy clamp to work properly.
To add to the woes, the engine assembler failed to pick up that it was a tall deck block and required a longer oil pump drive shaft .... that was hard to diagnose when a new engine loses oil pressure for no reason.
I got there in the end with modded accelerator links, better fuel line route, boost referenced carburettors and a proper harmonic balancer for a blower application. The install was challenging on this one but the end result was a sweet running engine with monster amounts of torque to hall this heavy full size sedan around the hills .... and cool looks of course.
