My friend just finished installing a powerdyne supercharger on his LT1 impala, He got it used for a good price and is in good working order, He was thinking of adding an intercooler, but looks like rerouting it would be very difficult, since the Condenser,Tranny and engine oil cooler are in the way..... Does powerdyne sell an intercooler kit or must one be fabricated?

If anyone has any suggestions on what plugs he should run with it that would also be great, With the blower, should he go 1 stage colder?
