IF one switched to DOT 5 silicon brake fluid in lieu of DOT 3 or 4, should "fix" a potential master cylinder fluid boiling issue....yes....???? Just a thought...

If I remember correctly I met a guy with a 68 that had max wedge manifolds on it.
He had fabricated a heat shield towards the front of the master cylinder, pretty sure he said the master got so hot it wouldn't work.

As I commented on the video itself, something just struck me wrong about the 440 itself - that
engine isn't very "happy", regardless of exhaust configuration.
As he alluded to at the beginning of the video, Nick didn't build it and didn't know anything
about what was in it - but that one needed gone through for sure.

Another thing came to mind about our 440 engines, The way the factory didn't machine the
sealing surface for the valve covers. I plan on skimming these surfaces before assembling
my heads so I won't have oil leaking on the headers! I've heard some of our members say
that their surfaces were all over the place, hence the leaks.

A tick over 400 horse and I bet the owner will be disappointed with that. Nick will probably build it before it leaves the shop. LOL

Same thing I was thinking.
The darn thing acted like there was a vacuum leak or the carbs needed sorted or heck,
even the cam was installed retarded or something - but whatever it was, it was surly at idle
and didn't put out the HP one with that sort of cam should.
Readers digest version: "It ran like ****"Same thing I was thinking.

A higher boiling point but not by much.
Boiling point
Dry boiling point Wet boiling point
DOT 4+ 230 °C (446 °F) 155 °C (311 °F)
LHM+ 249 °C (480 °F) 249 °C (480 °F)
DOT 5 260 °C (500 °F) 180 °C (356 °F)

The question was "boiling" of the brake fluid, not deterrioration of the master cylinder piston seals. Do we really know what component is failing? Perhaps you should consider changing these seals from viton, to perhaps polytetrafluorethylene (RTFE) or a fiberglass reinforced silicon.....just a thought.

What I read about the Tri-Y exh manifolds is that they were being developed for Nascar. But just as they were going to go into production Nascar made after market headers legal as did drag racing. And of course headers are so much lighter then Max Wedge manifolds all racers run headers. Thats the same reason I went right to headers as they are much lighter and make even more power so it was a no brainer on my street car. But thats why I read only a few sets of Tri-Y exh manifolds were made and they are heavy and very rare. There is pics of a red 64 Dodge Maxie car that has the Tri-Y's on it as I see the pics of it now and then. Ron

This one appeared to like manifolds even less than that one up at Nicks......

To put up a reference point for about what the motor up at Nicks might be built like:
This is a 446 with KB quench dome pistons, about 9.5cr, 346 heads with stock size valves and a very minor and quick bowl blend. Comp 280H cam, stock valvetrain, 6bbl, and 1-7/8” headers:

Nick says he still has trouble logging on here, can anyone help him out?
Tell him to try clicking the "'forgot my password/username" button, if he hasn't already. He'll get an email with the user and/or password exactly as the site has it, so he can make sure they match what he's typing on the log-in screen.
