How does the 1966 Dart engine bay take the hyper pack manifold into it? I have seen them still available in the Clifford site. There is also picture from an A-body where is one of those masterpieces installed.

In the example there is single master cylinder and no power booster. Does I quess right the dual master cylinder with brake booster does not fit without modifications?

Super Sixed, but still a bit hungry...

I have never used an H. Pak with power brakes but there may be a power brake booster which will fit, it will be tight. It would have to be one of the thin/flat type booster diaphrams.
I do know that the dual master cylinder will fit with-out the booster so you may want to just install a dual master cylinder and skip the booster.

I installed a dual master from a '71 Demon on my '66 and it bolted right on. The only thing was that it left a small hole in the firewall above the M/C, but a dab of black silicone took care of that.

One thing to note about the HyperPak is it doesn't get a whole lot of carb heat. Right now I'm driving my Hpak Duster to work everyday and averge temp here is between 30 and 39 degrees out, the only way it will idle is with a very rich mixture (anything close to 14.7:1 will not work). Consequently this has caused my MPG to go to 10-13 mpg.... I can only think of 3 things that would make things better: 1) more manifold heat, 2)warm air intake (this might also rob power, but allows for a leaner mixture/better mileage) 3)EGR

I noticed your from Finland, so I just wanted to 'pipe up' before you bought one and had one cold blooded slant, I think either the dual webber or an Offy 4 barrel intake with manifold heat would be a nicer choice...

D. I. I'm fighting the same thing in colder weather.Presently I'm working on a 232 amc engine and the nice thing about the offy 4barrel manifold made for that engine is that is a dual plane manifold,it should keep the primary mixture up to speed, a problem when using headers and a un heated manifold. Why is'nt there a dual plane manifold available for a slant maybe even a dual plane Hyperpack? any comments ?,Bruce Johnson

A divided plenum H. Pak works a lot like a dual plane manifold.

A little while ago someone had some pics up of some Austrailian slants, that had remotely mounted power boosters. There was a little discussion about it, I think in the "other" section. Anyone remember that? It would definately help if using power brakes and the h-pak on the same car.

I would try a 15/16" bore master cylinder before you add a booster. The smaller bore will require less pedal effort, but a bit more pedal travel.

Has anyone tried adapting a Ford/Lincoln Hydra Boost? It would offer all the clearance you need as well as hydraulic assist. Not sure if the standard steering pump could handle the load, not much flow would be required. You'd need some custom hoses and a hydraulic accumulator to make it work.
