LQ4 into a 3rd Gen/1972 Nova by frojoe

Made a mockup of the rad setup I was thinking of using.. a C&R 31" x 19" radiator, dual pass (inlet and outlet both on passenger side) which has the filler on the driver side. Along with dual 14" Derale fans that are ~2.75" deep.

I placed it on the old rad brackets just to see how high a 19" core would sit. Pretty up there, but the filler cap still clears the hood be 1/2". Think I'll lower it and see what the potential upper hose routing would look like.

Also test fit the upper and lower alternator brackets before I drill and tap them to make a 3rd bridge piece, which will support the idler pulley. Fit is very good.. looks like my 3D model of the LS3 is accurate. There's about 3/8" gap between the alternator and the subframe cross member.. good thing I have the 1.5" further forward truck accessory drive or else the alternator in this location would for sure need to chopping of the subframe. The 1/4" adjustment I built into the brackets via slots works well, it visibly aligns the belt in plane when set up right in the middle of the slots.
