Doesn't Stage V Engineering make Hemi conversion heads to use on a wedge block? I understand there is way more to it than that, but they are out there, right?
Yes they do , not very often but they do , it is not just a drop on and go though. You do need to still grind on the block for pushrod clearance, and you have to add oil drains to the pan. The upper row of head bolts is in the intake, this may actually be better than the valley studs? Then you need hemi pistons, that are a custom because the 440 is a .070 over hemi size not, including any overbore the 440 needs .
The hemi blocks aren't that expensive anymore to make using the conversion heads a viable option unless you have thousands of dollars into a 440 block in upgrade machining ...

Heck you probly wouldnt really even need the extra bolts for head torque unless you were going for all out compression.

 ... you seriously believe that ? ...
There is more than just installing the bosses , you first have to grind off the currnet casting bumps because the hemi botl is about half a hole up from the wedge threaded hole , you have to do something about the lower oil returns at both the front and back of the block on each bank back to the oil pan.
Then there is the exhaust pushrod tunnels , grind the 440 block and you hit water ...
 Well said John.
Laugh all ya want, I SERIOUSLY do believe they did that back in the day. If a machinist can build a TINY TINY version of any V8, they sure can figure out that small detail.
Hell Id try it for the wow factor alone.
That is if I had access to the parts to make it work, heads, and a lot of time.
Believe what ya want, I tend to think outside the box quite often, and have "figured" many things out that other shops have said is imposible.

I'm laughing at you thinking the bolt up there is only needed if the engine has high compression, I'm sure the engine would run without it but if you've ever read any of the threads on hemi intake leaks just overtightening the intake bolts is enough to cause a coolant leak , imaging what would happen if you tightened the intake bolts to the correct torque setting without that bolt there at all .
You want to make a hemi block out of a wedge block , go for it I'm sure it's been done in the past . Keep track of the hours it takes you .

I have had 3 64 Plymouths with the 426S, and every one of them was a slug. Well, maybe not slugs, but a strong 383 would walk them, and I have had more than a few 64 383s too.
Problem was the 426S was a mild motor, used the 413 New Yorker cam, had no better heads than the 383, etc.
With better cam, heads and intake would have been a different story.
Still, a factory 426 car would be a damn good starting point, more for the other stuff that came with the engine package. Think bigger (11") brakes, cop car(as good as it was) suspension (with front sway bar), HD cooling, and glam factor.
Wish my 65 Coronet convertible was a 426S pkg...
Wow surprised you were beaten by a 383. I had a 64
426S 4 sp in a Polara in 1965 and no way would any stock 383 beat me. I did not have much trouble with the GTO or 396 ss, until the 375hp SS came out. Traded it for a 67 RT. Of course it was a Dodge which everyone knows was faster than the Plymouths  Wish I still had the Polara!
