I wash my engine bay all the time, spray em down and get'em clean, i don't think you'll hurt anything.

Those fans cool very good, i can run the shit out of my truck at the track, just keep hot lapping it, and the temp will never get over 180deg. it can also idle forever and never gets hot, i really like the ls1/lt1 fans.

will your stock shroud fit over the lt1 fans shroud, my setup is completely different than yours, maybe cut the stock shroud and lay it ontop of the lt1 fans, i know some guys just find a good place to but small screws or bolts and just screw them into wherever there's metal, like the radiator support.

kevin mounted his, maybe he'll chime in and let you know how he did it,

don't you know you can't find any technical answers over at that other forum, lol, jk


good luck,

allen
