Longtime lurker and much respect to the mavens on this board. I'm always picking up great advice here. I've got a question regarding the Spal 16" high-performance fan (rated variously at 1,900 to just about 2,100 cfms). I've combed these threads and read that these are the best aftermarket fans available, so I'll go with them. I have a Ford F1 with a US Radiator 4-row radiator (copper/brass) -- core size 21 5/8" X 21". After installing a Vintage Air unit, my engine (305/Turbo 350) is running hot -- the small mechanical fan wasn't going to cut it. There is a shroud available from Classic Haulers that covers the entire radiator. So I'll be running the 16" Spal fan with a full shroud. Anyone on here go with a similar setup? Just looking for feedback from people with something similar -- not looking for anyone to predict the future. I'm in Austin, TX, and the heat is going to really start hitting soon. My friend advised me to up to a 100 AMP alternator, which I'll do.
