If you are running a late 70's L28 engine in an early 70's 240z, what is the best kind of radiator to use? Can you use a radiator from a 280z? Are they all interchangeable like the engines are? What is the recommendation. Thanks guys

Easiest to fit is a 240Z radiator re-cored with a 3-row or 4-row core. A 280 radiator will fit, but will hang down lower than the 240 unit. Holes in brackets of a 280 Rad may need to be "adjusted" (ovalled or redrilled) to match the holes in the 240 Radiator support. You'll need to use the lower rad hose for the original car the rad you use came from. ie 280 rad, & 280 lower hose, OR 240 rad, & 240 hose.

Good luck
