Not "Modern" flathead just geometrically sound.
The last one was a 221 punched to 240. Customer didn't want the extra stroke and settled for the bill of 4800. HP of 392/410trq.
No bottom end problems.
Glenn Schisel just came by to see if I was ready for his V-12 Zephyr project.
Flat heads are not my joy, too simple and too picky customers, but pay the bills.
Blocks from France are cheap and available. Rods, pistons, heads, cams, etc are affordable and plenty.
I grind the cranks as to the project. Stroke 'em, use common geometry sense and build an affordable peice.
Wanna 440 Hp unit with out blowing out the main webs? 4.5 stroke with a French block, easy cubes with a good bore, no problem.
Everybody worries about the three main web problem. Affordable caps and a good block brings an easy number.
Now, do I smell a challenge or were you just busting my chops?
