Sportscar365 has learned that IMSA has approved the use of a 5.5 liter normally aspirated V8 engine instead of Cadillac’s 6.2-liter unit that took Ricky and Jordan Taylor to the Prototype championship this year.


this 5.5L variant has been a 'mythical' "coming soon" size for years.  Interesting that it has emerged.
