ok guys, i have an 04 standard cab 5.3, and i am getting ready to install a set of ls1 fans. well i just measured my radiator and it appears to be a 34 inch. the fan shroud is 28, will the ls1 fans still work. and also is it ok to temporalily hard wire the fans so they are running all the time untill i get my nelson harness and tune? next month i am changing the cam and want to wait till then to get the ecu upgrade, any feedback much appreciated, thanx nick
