You might have to entertain the use of 2 3rd gen coolers in a v shape with a plenum exhausting aft kind of like what John Slade did. Also Aero classic makes a 19 plate cooler for AC applications Pacific Oil cooler site. What are the dimensions of a Cosmo cooler? Can they be found?

Cheers,

Two factors made it possible.

1. Used the early RV-4 FP prop cowl (40" FW to prop flange) which is about 1.5" longer than current version
2. Used the RX-5 Cosmo oil cooler which is shorter but wider than the RX-7 cooler, and has ports more conveniently located than the RX-7 cooler. It was a gift from my brother Barry who owned the RX-5 donor car.
