I bought a 16926 Derale fan for a 1966 Mustang (with 302 V-8) because it fits the radiator perfectly. It's rated at 2200 cfm and cools well in traffic. I liked it so much I bought another one for my 1964 1/2 Mustang. Pros: - Easy to follow instructions - Easy to install - Works as intended - Multiple mounting points are cast in Cons: - Somewhat noisy; 2200 cfm is LOTS of air! Create your own mounting brackets for the best look - all terminals are crimped; You should really solder all connections to avoid over-resistance and hard circuit. Since the system is ground activated, you MUST make sure all circuits are well grounded or the system will melt! - A 30 amp built in fuse is pretty cheap - replace it with a 30 amp circuit breaker before installing. Do not use the included temperature sensor - purchase the Derale 16749 Adjustable Fan Controller for custom temperature settings.
