It seems from my search that the concensus is to go with the larger, aftermarket fans for the 6.0 trucks. But most with the 5.3s go with regular, readily available and cheap ls1 fans. Has anyone used the LS1 fans in a 6.0 truck with success? It sure seesm they would work fine to me. I have a 385 ci 6.0 block in my SS with 11.5 to 1 compression and regular LS1 fans and it never runs above 190 in stop and go traffic.

Any other reason I may be missing NOT to use the LS1 fans? This is on an 01 Sierra C3 extended cab shortbed btw.
