I modified my fan to fit in. I carefully ground off each blade what was needed (I even needed to grind more off because I put a 2 groove harmonic balancer in my 261 and it definitely hit the fan). Then I balanced the fan to make sure I wouldn't have any weird vibrations (I saw a fan blade let go once and it made a nasty hole in the hood). Very carefully examine your fan to make sure absolutely no stress cracks are present at the rivet points.
As far as the fan hitting the shaft, you'd be surprised how "untrue" your original support may be. Torturing the support to fit the sheet metal and radiator will require automotive chiropractic work. I have a hefty 3/16" clearance between my radiator and water pump. So I used the best possible parts in that a part failure will result and one wasted radiator. Finally, you say new radiator. I've seen more new radiators not fit than do fit. I can only guess the QC is not where it needs to be. I always use original tanks and mounts and recore it to make sure it fits. What I mean is don't assume your new radiator is an acceptable fitment. Good luck.

I have a 53 Chevy truck that I have been building for quite a few years now. Finally I am ready to get it on the road, but as I try to install a new radiator it won't fit. Let me give you a bit of background: I am using a 1957 car engine, I replaced the water pump with the short shaft water pump, I have the original radiator support core, but as I try to slide the radiator down, it rubs against the shaft of the water pump. Also another problem that I have is that the fan rubs the crank pulley and it would need to be about 2 mm shorter to miss it. I am sure this is a common problem faced by those making this upgrade, how do I go about doing this? I don't want to have to hack the radiator core support, I have a spare core support (already hacked) but still I can't see how I can get it to fit. Do I mount the radiator on the core support before I install the core in the truck or afterwards? Would this make a difference? Thanks for you help.
