Anytime you build an engine outside the normal sbc or sbf area, you are going to spend more. I could have built 3 Chevy small blocks for what I have in the 394 Olds in my '39 Dodge, but the wow factor makes it worth it.

I only mentioned the cost of building a flathead so you go into it with your eyes open. Also, finding a suitable core to begin with is tough.

Good luck.
