Vacuman. You have also had some nice cars. Did the Corsair have the 3.0 Essex V6 in it? I had stage 3 heads , different cam, rocker gear, Holley 4 barrel and a custom made twin exhast system on my Mk1 V6 Capri.
When I had my Lotus Cortina I bought a new big valve Lotus engine for it and it was also one of the first to have electronic ignition fitted. It was a quick car but not as brutal as my Uren Savage! Look at how much the Mk2 Lotus Cortinas are worth now,£20k or more is what a good one will set you back now!
