best way to know is go to advanceautoparts.com or napaonline.com and crossreference the p/n's for the parts and see if the match or compare pics

I believe the bucket assembly is different but not sure on the pump itself

They are different. the LS1 pumps have an extra hose coming off the pump. You could make it work I suppose, but I think you'd be better off using the LT1 pump.

$125 is about what I paid for my Granetelli kit. You are referring to the kit w/ a 255lph Walbro pump right?
