Thanks Charlie. How's the project progressing? I'm still thinking about a turbo and relocating the radiators for a cleaner airflow.

Do you have any pictures of your engine mount you can share? Particularly the lower rear attachments to the engine block.  I remember you had a unique solution but I don't recall the details.

Bottom view below. Note that the square tube that connects the two 'tripods' on the firewall side would have been more functional if it had been welded between the two adapters, with the sleeves welded to the two 'tripods' on the firewall side. The reason is that the square tube would have provided a hard connection between the two adapters, removing any risk of 'racking' load on the bolts/studs attaching them to the engine. That's how I'd have built it if I'd not been too dense to picture what Monty Roberts was trying to describe while I was designing & building the mount.

The adapters are *way* overbuilt; most of the parts could have been made from .062 instead of .125 4130.
