I've been doing Track envents for about 15 years..both in a boat anchor FE (ala a427sc) and the much more nimble and quicker FIA...with ittsy bittsy 289....as the skill level and disire for "more" increased, the safety aspect was of consern...The cobra will be kept as a open track car only....I'm having a 66 Shelby built for Vintage racing ..with top...side bars...full chromoly cage....
Bottom line....open cars will never be a safe as something with a top and a cage....just my opinion..
Don's FE is very safe....to slow to be dangerous....unless he gets run over by a "little car"..... hey buddy...coming south this year?
Insurance cost is driving everything....even vintage racing. Much more time is being spent on safe cars and "legal" cars...most vintage cars are faster now than in the 60's due to "big" brakes...."big" motors...etc. If there are bad accidents....insurance cost will increase...more rules will be imposed...
Bottom line...."be safe"
