90mm cosworth forged pistons and bronze sculling in the heads[Linked Image]

It would have been a bit of a monster but i ended up swapping the bits i had for a norton belt drive kit for my tribsa. I was never going to be able to make it work. I think thats what the crank may have been used for, the cases that suit the barrels in picture i never had but they were possibly available at some point back in time!

regards

derek
