Aluminum Radiator from Ledfoot Racing

I saw a few cheaper ones too, some looked exactly the same as the one from Ledfoot, but it seems all sellers are from CA, so I have to pay tax... :(

Most all good radiators disappear from the junkyards here fast (just like posi carriers, rack and pinions and good bucket seats) no point looking there unless I can go almost daily - nothing good or valuable hangs around too long

Originally I was thinking about the summit branded alu rad for $159, I have one in my '59 truck and it works great, but then I'd have to fab up brackets and run a separate trans cooler - for a few $ more this one should bolt right up

Would love to hear from anyone running one of these, specifically how much more efficient you noticed it being over a factory rad
