Inquiry (采购产品): Superceded pump; Parts & Repair (Nevada) Urgent request for all pertinent info regarding GM applications concerning the Ls1 thru Ls7 engine series. New pump for Ls2 (Ls7) flow characteristics, metallurgical dynamics,etc. versus previous model. More to the point, I have one of each and GM has been somewhat vague (surprise) as to the merits of each pump. I would be SO grateful for any enlightenment you could provide. My Mr. Goodwrench buddy more reminds me of the soup nazi these days :) LOL--Thanks, Brad ps...catalog, maybe too? **** Hidden Message ***** BRAD QUENEMOEN 89118-1207 Company: SUMMIT PERFORMANCE E-mail: ntprowlr@cox.net **** Hidden Message ***** ntprowlr@cox.net
