Not long before the engine can go back in now.
I am having custom made S/S complete exhaust systems made up, including 4:2:1 manifolds, and that is not cheap.
I bought 3 fans from Maplin, and have screwed them direct to the two vents, and the heater matrix, in the plenum chamber. That way you can blast hot or cold air where you want at the flick of one of 3 switches, and you can put luggage in the hole without affecting the airflow too much.
When putting luggage in the front, don't make it too heavy, or it can jam the throttle open. That happened to me in 1978 in 75032529P, my original car. I am lining the front with 9mm MDF and a black carpet.
