Projects Flathead Flat-o-matic how much$

Have a 42 Ford Flathead 8 I see a lot of people have positive remarks on this conversion.
There website does not have any prices. I realize there are different kits depending on what you have.
Just looking for an estimate, saying I will already have a c4
Thx

 

If you are talking about a C4 to a flathead kit, you are talking anywhere of $400 to $7oo, depending on where you get it. I got mine from Speedway for $400.
