Hi Joe, the company I used for the castings have reproduced car heads and blocks as well, so no doubt that they could indeed reproduce the sandcast cases too. But it was a considerable cost (I think they had a guy on it full time for almost a year to produce the moulds for this one job)....
Im not sure costwise, it would work. To recover costs, I would see a need to produce at least 100 sets of cases, then machining costs too on top of that, which would make the costs of the cases high. For the approx. $1200usd cost of buying a set 2nd hand, I think it would work out a lot cheaper, and of course, original
Thanks for the feedback guys.... a bit of a delay on getting the final bill (this is the one time I want to see a bill!) so I cant firm up prices till tomorrow.
Regards,
Steven.
