about 12-15 year ago those where the good dual fan worked well seen a few at the drags. If your rad is the smaller style rad small block fit ok. If you have the big block large rad 73-80 and 81-87 tall but not as wide it may not fit the rad as nice. To get best cooling you may need to make a shroud adapter funnel air throw hole rad. https://bowtieguy.proboards.com/thre...nting-brackets This show the break down of the rads in LMC
