Surprise surprise...the wide 2 row these guys suggested put you in the same place you were before.
These aftermarket radiators must have some goofy side brackets that are pushing the core too far back.
Or what is the actual distance between the fan and the radiator core?
Are you running a thick billet water pump pulley?
Where did your fan come from? Wonder if it’s too wide
A stock radiator with a high density fin count core made by a good radiator shop would allow you to run a stock 7 blade fan and the 2947 Hayden clutch and a stock fan shroud. Unless your motor is in the wrong spot.
These generic aluminum radiators require the purchaser to have the skill to fabricate and engineer:
-fan shroud for mechanical fan
or
-electric fan (preferably OEM) with fabricated mounting and electric supply
