I am in the process of mocking up 29 Ford Tudor. This is what I,ve got. TCI chassis, 327 SBC, four inch recessed firewall, Walker rad with AC condenser(4" thickness), will be running a smaller diameter HEI distributor. I,ve got a mock block and trans bolted together, thier just hanging in the frame right now. I want to make sure everything fits before any welding is done. With everything in place(3/8" clearance distributor to firewall), I have 1 1/2" from waterpump nose to rad. I don't think thats enough room for an electric fan is it? I see all those model A's out there with air conditioning and the four inch recessed fire wall, and running electric fans, just not sure how they do it. I'm just going to run a hood top (homemade), so I could slide the rad ahead a 1/2' maybe. I don't want to move the engine back, it ruins the look. I could go smaller rad (thickness) but then where do I put the condenser? Anybody out there with model A's that can offer advice? Great informative site, sorry about the long post.
