Last time I had a motor all balanced up I used
Halesowen Engines Ltd
They do no there stuff

And it's funny talking about cam shafts
When I spoke to Stu at MSD and told him my spec
With 2 BD14 Cams he told me to pull the exhaust cam out and stick a standard can in it's place .
And iv been told that before by a top engine builder . I'm planning on 500bhp and in booked in at MSD on the 1st May but it doesn't look like it will be happening now
