I've been very happy with way the car is performing, but, oddly, I want more. Since the car is nearly 50 years old I am considering replacing the rear springs, installing a panhard, possibly changing from the Armstrongs to something else.
Yep - did mine - new 4 leafs from BCC, Panhard Rod and overhauled the Armstrongs and fitted them with adjustable damper valves (from SSL) - much cheaper and less hassle than going for a shock conversion. Transformed the ride. Not quite a 'straightforward job' - the 4 leafs moved the axle back (now perfectly central in the wheel arch) so had to move the Armstrongs position on the mounting plate, and move the tank back a smidge.
I'm not ready to do a cam or head at this point, but have been thinking about doing something with the stock distributor.
Replaced the FoMoCo dizzy with a refurbished H&H Electronic Lucas Dizzy and Dry Cell Coil. Has proved very reliable. If you have a bit more cash, the 123 Ignition Dizzys are multi-programmable and have a good reputation.
