Dear Dawg;
That's correct, Sir.
The 216-235-261s all have that
basic head design, with little
change from It's beginning in
1937, till ending in 1962.
--------
Wayne & Harry 'teamed up' after
WWII to build the 12 ports and
all went well till the SBC 265"
V-8 came out in 1954.
After that; the "muscle car" era
began and the 'flatheads'/'sixes'
all took a "backseat".
-------
They just tested (engine dyno) a
377" small V-8 on pump gas (9:1)
& a single 'quad' with 506 HP @
4,800 RPM...
It's really tough to get 1 HP per
CID with the early sixes. Even
then; they have a really short
lifespan and cost over $4000.
Most do it still; "just for fun".
Good luck.
