If you go to u tube and watch GOODWOOD VINTAGE RACES you'll see one racing and while not blowing the Jags etc off does function well.I guess it's limited to the anemic carb it came with~~! I think it can upgrade to 4 CR speeds, sprite disks and a header if not the bigger SU's It probably doesn't weigh much more then a sprite so with 1500cc's can stand a chance!Restored a "58 Met--engine---tranny--new interior--brake system--black and white paint-great fun--
