400 stroker build....for a boat

I have a couple of 470 engines which I use for dyno testing. They are a super nice combination. If you were closer I'd tell you to come over and take a look. Here is an article I did for the Hot Rod website: We Test Intake Manifolds and Carburetors on our 400 Stroker in Search of Ultimate Power - Hot Rod Network

It should give you some details on building a 470. I also wrote a book on big block Mopar engines which you can buy at Amazon: How to Build Max-Performance Mopar Big-Blocks: Andy Finkbeiner, John Baechtel: 9781613250921: Amazon.com: Books

Between the book and the magazine articles you should find all the info you need. By the way, I'd use Trick Flow 240 heads on your engine if the exhaust system will work with angled plugs. If you need straight plugs then the task gets a little harder.

Molnar has the crank and rods that you need, multiple places have the correct piston. Everything else is just standard bolt on stuff. No low deck EFI intakes available so you'll have to roll your own. Wilson Manifolds can do the conversion. I'd recommend starting with a Trick Flow intake manifold.
