From my searching here, I gather that F body ls1 fans with 28" obs radiator and 05+ truck fans with 34" rad are most popular. Three questions:
Anyone mind posting install pics of one of these setups or some less popular OE setups? I am not interested in any aftermarket pics. I am dead set on creating a very factory looking install.
Next, this is for the 92Sierra swap. LQ4, cnc and welded chambers 317 heads, cam, springs, push rods, LTs, dual 3" with Magnaflow X muffler, 80e, stall vert. Don't know compression ratio yet, maybe 10.5? Don't know cam specs or stall speed. Heads are at Advanced Induction getting worked and soon they will release cam specs and stall recommendation.
All that said, what are your opinions on rad sizing. 28"obs or 34"? Is a bigger rad TRULY necessary? Fans will be wired for two speed. He is in Ga where summer time temps do reach 100°.
Also, has anyone kept the factory obs fan shroud with either of the above popular fan/radiator combos. I would love this if its possible. Thanks guys! Pics please!
