The Cobras were all required to run with hardtops.

COB 6008 (131HYN) used side-pipes

Bill Murray entered the Revival a few years back with a 427 and was forced to run in the prototype race (Whitsun Trophy) matched against Lola T70s and GT40s etc. due to period homologation. The 427 was homologated by the FIA in 1966 as a prototype, not a GT car due to the required numbers of cars not having been built. The 427 is of course outclassed in that category but in Bill's case, it was not for the want of trying!! He came home 13th overall, but I've never seen a 427 driven so hard.
