It will take probably more than just plate change. The plates would need to be thicker perhaps and would need to have TP tubes would need to be fashioned in so I would think the runner may even need to be bigger,certainly round. I would have to send him my mainforld to pull dimensions from. An even better way would be to send him my block and heads too. I realy don't have the energy anymore.
Now if I had the money to order a new SPF GT40 and build another alum FE I could find the energy real quick!
I really would like to find a piece that was totally sorted out in terms of fit. If off just a hair then the pushrods might rub or
oil leak out the back.
