Issue with lower rad hose rubbing on suspension
cut 2" off pump side and stretch hose off that interference point. Then make a shroud. Let that fan pull through 100% of the rad. If you go electric get the Taurus style double fan and shroud assembly. It will cover entire rad and pull with 1 or both fans*. Wire it up directly to battery via a 50A relay as it pulls huge amps on startup, run the relay voltage to a cheap *Hayden rad thermoswitch so its not on while your cranking.
