Skye:
Data for the MGA twin cam from the December 1958 issue of
"Sports Illustrated." SI felt the car wasn't performing as
it should so later they did a complete rebuild with Hambro's
permission. According to a seat of the pants test
afterward, the car was faster and more responsive. So the
data below could probably be bettered with a carefully tuned
and assembled engine, but still stock.
