I know of two 100/4 Healeys which have had their 2.6 litre four cylinder engines replaced with 350 Chevys. Not an uncommon swap which can be accommodated under the standard bonnet. All very much in the early 289 AC Cobra mould. One of these has more recently been fitted with a 671 GM supercharger, which rather destroys the sleeper illusion!
