Hello, the car is a 1972 Ventura. I originally had a be cool radiator with two one inch tubes, the radiator is 26X19" and the core is 22X19. I had a 2700 cfm electric fan with a shroud on it and the motor would creep to ~230-240 and I would shut it off. The weird thing is that if I let the car sit at an idle, and dont drive it, it never gets over 200. As soon as I start driving it, it slowly starts creeping up. We figured that the radiator must be clogged as it was an old radiator so we bought a new triple pass FSR crossflow radiator. We are still using the same fan and shroud and it runs a little cooler, but still gets to 220-230. I am wondering if a mechanical flex fan with a shroud would have a good chance of solving the problem. I think the electric fan and shroud may be causing more airlfow restriction than anything and that the mechanical fan would help. Below is the fan and shroud I am thinking about as well as the fan and shroud I currently have. Does anyone have any experience with a mechanical fan and shroud like the one I am looking at?
This is the exact fan and shroud I currently have.
This is the flex fan I am considering
This is the shroud I am considering, I may run two, one right side up on top and the other one upside down on the bottom.
If it matters, I have a march pulley kit with a long water pump
