Here's a picture of the new Aluminum Flathead block that I took at Greenfield Village this year during the celebration of the 32 Ford and flathead engine. This is the one by Mark Kirby of Motor City Flathead and his new partnership. If I remember correctly is it a 3-1/2" bore and a 4-1/2" stroke. The cylinders are all sleeves and I think it had four or five mains instead of the usual three.
I wonder if the sanctioning bodies will allow it...If I remember correctly, Bonneville rules won't allow the French blocks. -Brad
Did anyone see the working..I believe 21 bolt aluminum flatty one guy had on display at the corporate headquarters? That was cool too.
