This is its twin sister. Doin work.That doesn't look like too bad of a fix. You should show us how big that monster really is!
Wonder how much power it takes to run that fan?got a 97 C3500HD.. freshen the 454 up, been working at updating the cooling system.... mainly the fan... and thermal fan clutch..
swap in a hayden clutch, does well, better than stock... AC at idle sucks... air flow is drastically reduced.. pre condenser fan would hold a 3*5 card at the edge of the radiator at idle
OEM fan is 20" 9 blade with 25* pitch and 1.75" thick blades.. assuming pitch is measured angle in a straight line from leading to trailing edge of the blade..
to a derale 20" 6 blade, 27* pitch and 2" thick blades.. pending mounting bolt circle... pretty sure 3.5" is a typo and is suppose top be 3.25"..
currently running solid hub 19" 6 blade flex a lite which move substantial more air than OEM setup... holds said card up easily, also pulls ~50* out of the condenser at idle in 80* ambient between inlet/outlet ports
im sure the 6 blade will talk more when engaged than the 9 blade will
