RickLake: The Lister was a one off race car. While very fast, and I agree with you as to its performance, it was built in very limited numbers and was never intended to be sold for public use on public roads or homologated. The Maseriata birdcage, also was a dedicated race car and built soley for that purpose. It was never homologated to my knowledge.
While again the Maser and the Lister were very fast I don't believe they would have competed against the other three in the FIA World Championship series. Let me know if I'm wrong on this.
I chose the 250LM, Grand Sport Corvette and 427 Cobra to compare because it was those three cars that each of the respective manufactures (in the Corvettes case the Skunk works Chevy guys were hoping the guys on the top floor would build the car in sufficient numbers but as we all know the stuffed shirts at the top drove a stake through the heart of the Grand Sport project...sad) was hoping to get off the homologation runway in time for the 1965 FIA World Manufacturers Championship series for GT class.
Also I believe the upped the displacement on the LM so we would have to compare the final iteriation of each as they would have stood at the beginning of the '65 season and as they would have developed during the season. We can kinda take educated guesses where those two end point would be.
In my book the Cobra's with the Daytona's for the track in Europe with the longer straights would take the Cup at the end. It would be a dog fight but my money would be on old Shel' especially if we keep Ken Miles in the mix.
But hey, I'm admit I am biased towards the Cobra.
