The v6 and I6 motor stands sit in the rear mount holes, while the v8 stands sit in the front set of holes. My small block is in the 6 cyl mount location. This is because when I swapped out the 351 V6 I didn't want to move the transmission, lengthen the driveshaft, etc. I suspect that the others prob swapped out I6's since they are more common. To solve my fan distance issue I am in the process of mounting up a 16" e fan/shroud combo out of summit with a thermostat.

Looks as if everybody that posted pics of their mopar e-fans has them dropped in a few inches.
Had no reason to mount it where I did, but I have noticed a small amount of cavitation. Plan to mount a speed controller to see if that helps

You seem to have some knowledge on the subject, why do you state moving the fan out will work

Re: Radiator Shroud

ok, I used shorted brackets which brought it back a bit. The brackets hold it very securely, however when I put 3/8" of sponge-rubber weatherstrip around the outside edge, I thought I was going to need a huge press to get it in! Finally with a bit of clamping I got it to set perfectly. It would be a struggle to get it out... so hopefully this will keep temps correct. Shouldn't be to bad if I need to go back to the original, best of all - NO HOLES IN MY SHROUD!!
I fired it up she's definitely a sucker! Hard to tell how loud it will be in the truck, a little loud now but it's very quiet around here.

Any idea what the cfm rating on this fan is?

Nice work! Don't know the CFM, but I do know mine really SUCKS Are you going to install a relay? Supposedily, these can pull 80 amps at start up
