Putting this out for feedback - cost effective, all new, and minimal fabrication work is my goal. What capacity, thermal efficiency, air flow, or other pros/cons do you anticipate?

I bought this radiator from Advance Auto, part 433730, to check fit, it is about as wide as OEM, and about five inches short. It has a tranny cooler in tank on pass side. $150 w coupons. It is listed/findable under a 1980 Chevy K30 with a 454 engine:

I bought this oil cooler. It is searchable as a 1985 RX7 engine oil cooler.

I have a 455 with the early version 80% fan shroud. Radiator core is exact same width as TZE OEM, tanks are inch narrower each.

My situation was such that I have to do new transmission cooler and lines, new oil cooler and lines, and engine coolant radiator anyway. I wanted to cut the support frame for easier removal if ever needed again. Most of what I am having to do would occur even if I went back with an original/size shape. And there is the cost - If you went with a more standard, square, external oil cooler this could come in under $200. I wanted the oil cooler in the gap left by the smaller coolant radiator

The coolant radiator will be flush to original frame top, the tranny cooler is internal on passenger side, and the oil cooler will occupy passenger side 2/3 of bottom gap, with an air dam built for driver side bottom gap (about 16x5 inches). Plan is to make oil cooler removable separate from main engine radiator when I do the frame split.
