The engine parts can be bought from any speed shop or sngine builder.

Ateco (847)623-2737 has all the specs and has built a bunch of 500's.

Best price I have found on Merc impeller kits

I have always used Summit Racing for the other parts in the past. I knew exactly what parts I needed and wanted. If I was going to do something again, I would definately give rmbuilder and a few others here on the board a call to check pricing.

I bought all of the above and more from rmbuilder when my 557 build was under way. rmbuilder aka Bob Madara's prices will be more than fair. Plus he'll accurately answer any questions you might have 585-654-8583

Wow, that's about half the price I paid at the dealership. Good resource.

They have a huge selection of parts at very good prices. The site is kind of a pain to navigate though.
