lookin good, very nicely done!! .... the fan pulley looks right, maybe you've got a shorter nosed aftermarket water pump - you should be able to get a 1.5" spacer and get up close - a bit fiddly to install the fan, but that's what they make open end/box wrenches for - with that original shrouding it shouldn't be overheating, you might want to check the rad is 100% and flush the block
that shroud you got is designed for the rad in the 6cyl position, sorry, but you'll never get it to work for ya
