says they fit 34x17 radiators...but they dont look like the 05 silverado fans Ive been looking at.
i need something to flow enough air over my ls1 and keep it cool during slow cruises. Anyone know anything about these particular ones? will they work for me?

 

Yea they look like GM fans to me do you have the larger rad you will need it.

 

these fans are off of an impala

 

nevermind turns out they are for a 28" afterall...thanks for the info guys

 

Get a hold of some 98 camero e-fans, they work great on mine. I live in texas, weather is constantly at around 90-100 degrees. I got mine at a junk yard for $140.

 

yea ive already got a set of f-body fans but Ive been thinking of dropping in a larger radiator/truck fans if I can find a good deal.

 

www.gandrautoparts.com call the 800 number and ask for Greg. He has complete 05 fans for a good price. Plenty of peeps from here have a set from there...

 

Im going to be using the LS1 fans with a 34" radiator and other are running this setup with no problems.
