I saw this on the AlfaBB site yesterday.
I've always wanted to do this but try finding the spare monty engine(and cash!) lying around!
The weight bias must be interesting. I mean the standard 105 is a lead tipped arrow at best let alone putting a v8 up front.
Still think it's fantastic.
Injecting that engine would solve the bonnet clearance problems .
