Great thread! Had no idea the S65 was used so widely. I'd love to see more of that Judd engine...they are amazing. Not sure which V8 this is...
Anything on the Dinan S65? I remember when Ganassi was winning DP in IMSA every year with a Dinan S62. Before the merge (2017-ish?), Ganassi has a Dinan S65 ready to go but ended up never needing it. Then Ganassi switched to the Ford Ecoboost.
Who would have thought a 20 year old engine would still dominate?
