I’m not sure of total numbers but they were building 4 Alfa engines when I was there. A mix of the 6C and 8c. The 6 was I think £165k plus vat. Then they had a very early Aston engine (the technician was cursing the poor casting work, they were using the original block for this one, but it was wonky). Then two miller/offenhauser engines that they have been making for three years! We heard one of them run on their fancy dyno. They also had a couple of engines ready to go to customers. So really a surprising amount I thought. I assume the gearboxes they make are probably similar. These were all the completely new engines (apart from the Aston) but they were also working on others as part of their restoration work. BRM H16 anyone? They also have a customer who wanted an Alfa Flat 12 installed in his Alfa 3000cm. This was I think only ever a rumoured combination in period but he wanted to see it done!
