Overheating issues with remanufactured 360

Why is there so little clearance between the engine and radiator ? Seems like no room for a good clutch fan . Is the engine mounted in the right place ?
I run a 30 over 11.3 :1 340 and it never overheats , factory rad clutch fan and shroud . This weekend took a 100 mile cruise and it was 93 degrees , no problems , not even sitting in standing traffic for 1 hour . I was melting , car was fine .
