I can't imagine it ever being "cost effective" to do - has to be a complete labor of love where the amount of time invested comes from individuals with a passion and probably not a viable "new product introduction business plan". I've made a lot of those plans and spreadsheets - the numbers tell the story and they probably wouldn't be good in this case. BUT, when one has a lot of time, knowledge, computer software, skills AND relentless passion . . . things can get done! Go Ray . . . Go!

.......and yet unusual stuff gets made every day.
I think this should be a co-op with Ford themselves. For gosh sakes Ford is a leader in large casting technology.
If there is any engine that could use some updates it is the Ford Flathead. There are tons of Flatty's going together every year.
If Kirby's project didn't pan out the way he hoped at least he showed us the benefit of an improved design.
Do you all realize for example that Kirby was able to squeeze in a 3.5" bore by reducing the head bolt size, which gave him room for the bore periphery?
We discussed that one time and he felt that the original headbolts in the Ford were too large and unyielding. Instead of stretching to provide clamping force they warped the decks. I agree 100% with him. I would bet money that a longer "torque to yield" bolt of smaller diameter in a blind hole would be a vast improvement and make more room for a bigger bore at the same time.
