i have a 99 gmc 5.3. I have a polished K&N intake, i was wondering if there were any supercharger units that i can install but still keep my intake.

What is the best sc for my truck?

 

The best supercharger hands down is the radix. I don't know if yoiu can use the intake on it becasue the radix replaces the intake manifold and relocated the tb more to the side instead of infront.

 

Radix for sure. K&N tube is NOT re-useable. Magna supplies you with a new one. However the the K&N box and K&N filter will work with a little modification w/ the radix system. Im using it. Check my sig for pics.

 

I have a 99 5.3. What heads would work excellent for the money. Would West Coast Stage 2 heads work pretty good? They include cnc porting,valves,springs,guides,retainers,and a valve job...and theyr are all assembled. Could i just drop em in and bolt them right on? Would i need to get anything else to make them work? Would i have to get a tune or anything?

 

Im going with 6.0 stage 1 heads and spending the difference on a blower cam. Guess It just depends on haow far you want to take it. A guy near me is going to do a stage 1 for a little over $100 per head and I can get the heads for $250-300.
