Big Block Fan Shroud replacement

The 614 shroud bolts right in my 67 w/273. Mounting kit is just hardware. No brackets req'd.
I remember reading somewhere that the big block fan center was a little different from LA. Don't know if that's true or not. That big block owner installed the slant 6 shroud upside down long before the aftermarket offered the "melting" shrouds. I know the center offset of the slant 6 fan and that shroud ( 049 or 094 I forget ) is almost exactly opposite the LA so I assume its all true. In the end, I agree the 614 will be your best shot ( hoping it doesn't melt ).
