I have a 29 Fever with a 575 SCI engine and in process of a upgrade to the engine with AFR heads, new cam, Hadin marine exhaust, new pully for the super charger and programming the ecu. My engine builder and I have discussed a Whipple inter cooler and super charger kit. Has anyone done this to this engine? Pros and Cons?

I don't think you can go wrong with swapping the heads and cam
On the engine. I personally would skip the blower pulley and intercooler and go with the dyer blower 6-71 mod.

Thats gonna be a fast fever!!

Thinking about skipping the Whipple stuff and putting an IMCO 2 inch shorty to pick up additional speed also any thoughts on a different fuel delivery system than those throttle body injectors. looking to hit 90 MPH.

Talk to Eddie Young. He developed a new fuel delivery system. He just posted pics of it on Facebook. Based on many conversations with him about 575's, the limiting factor of HP increase is the TBI setup. His new system overcomes the TBI restriction.
