If I may be so bold. Just a suggestion. Every year at PRI they raffle off a motor for charity. They have the motor prebuilt to what ever spec they want. Tickets are sold and the raffle is held at the show.

Now since Dan cannot have the motor prebuilt and we need to help him out, Let Dan spec a motor out. If the raffle winner has no need for that engine he can sell it, or donate it back to Dan or what ever. Carlisle does the same thing.
This way people such as myself can donate PARTS to the cause ahead of time to hedge the cost of Dan having to buy what ever parts he will need.
May I suggest a big block pump gas 500 incher.
Just a thought...Todd
