I sold my 01 GMC and I have the Whipple for sale on EBAY it end in about 7hrs fits 99-01 GMC and CHEVY trucks and SUV's with 4.8,5.3,6.0 L ls1 style motors. If any one wants one in like new condition let me know. They can save some money on this one versus a ne one. Retail is $4299 I am wanting $2800. <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" />

 

Does it use heat probes? Is this an one serpentine belt runs everything including the SC kit, or does the SC require its own seperate belt to be driven?
