Supercharging a 1999 blazer 4.3
 

What type of superchargers are out there for these 4.3's and what do you gain with them? thanks for the help.

Set a budget... and then look... will save you a bit of shock and awe

powerdynes and wynjammers are so/so

Try to find a vortech one.

Re-reading... for similar prices... you could set up a nice v8 conversion. LS style 5.3 would be pretty sweet...

just bought a blazer with the wynjammer Love it so far. not sure exactly gain of HP but there is clearly a difference
