Early Mk II Spitfires had the smaller cam followers running on the best
original Spitfire cam (a 212164 with 25-65-65-25 timing) which was fitted up
to 1972 with big followers. Fitting this cam, raising the compression and
running a long branch with twin carbs will give 67 bhp. At present you have
perhaps 50 bhp as the Herald engine is 39 bhp with a single carb. Decide now
if you want to conver to a 1300 or 1500 engine.
