Was hoping to get a reply from you Roger regarding the Healey Corvette's standing 1/4 time. From memory it was 16.8.......I am sure a standard 100/4 would do that......a lot of work installing a big engine for very little gain.....I seem to remember Dave Silcock racing against it in its day and commenting on how 'slow' it was........the word slow being relative........Nice looking machine all the same.
