Dual action booster and front disk upgrade

I have been followng past posts on the booster upgrade conversion for some years now, always thinking of changing mine to a dual booster front disk conversion.

With these past existing posts I know of the panther conversion project and with that I feel that a 7" dual booster is just not enough for a panic or hard stop on a 4,500lb. Car.
With more cars and people walking on the road today I am wanting to do and upgraded braking system.

I currently have my motor out and thinking of doing an up high firewall mount with an 11" dual action booster.I can get away with this mount fitting and leaving my air vent intact and having the straight 8 leaving some pedal fabrication and thats ok.

Also with the front disk conversion I do know there are kits out there for a price but, does anyone know of any common domestic autos that can be used weather slightly fabricated or not. I once talked with an old packard guy with his 56 executive that swapped out with a 1970's Ford Bronco with leaving only a slight difference in the king pin to be milled.
I can no longer find him to ask...

I am only doing this swap for one of a few reasons; as our population and clutterness grows everyday around us i feel it is needed for improved stopping, easier access I am not going for any original points on the car but I'd like for it to be around in the family for another 60 years....
Any inputs are welcome....

Any updated replies from the people that went with the 7" booster conversion,how well of a stopping performance do you have with the 7" booster on a panic stop?

Thanks, I had to go look again; I guess I do not then! I do have controls to work the vent doors Right and left and on the other side the Temp side control says Air which means air control although that cable dose connect to a control box that dose have a wire coming out of it going to a hidden location. Although all this will be in the near future to attack..



For right now I am having timing issues and I believe it just has the wrong cam in her, the opening and closing of the valves just do not sync with the timing mark on the cam timing gear. To get them to open and close near where they should be that gear will read 180 off the Crank TDC mark. (just baffled)..

Funny you mention that... I have been staring at that box thinking the same, I do have the factory a/c controls in the dash not knowing if there is any kind of 6v relays or switches sitting behind it. I haven't got that far into it to look yet!



48' is 6v did you convert already? for the 56 is 12v !

Food for thought Was the idea for running to a junk yard And finding something comparable out of a GM! To pull all A/C and 12v Charging system Parts/brackets, pulleys, fuse box or whatever after I take my measurements. There is plenty of room to mount without having a crappy look to her. I would probably mount the 12v battery and fuse box in the trunk before the rear axle, It can be done neatly. and still able to run other stuff out from the Fuse box. I just have to watch the positive ground feed for the 6v side.



There is a world of parts out there fairly cheap waiting to be used again, that are still in good shape! She is a Original car and been with me in the family for 45yrs not looking for any points just to be comfortable.

There is also this option;

There is an elder man out here that has endless Packard's and a lot of other autos, he does do a lot of work on other cars from the car meet. He had rewired more than a few cars to 12v. He was telling me that the starter of a 6v system will handle 12v and probably more but to watch to long of cranking.

On his 56 Executive for the push button shift he had reworked it to work on a hydraulic shift that they use in aircraft, as he is a retired Air Force mechanic he is familiar with the operations, What a Ride!

Wow thanks for the blog! I had often thought about upgrading the Trans with more shifting options. I had actually stood over a 200r4 looking down at it one day years back thinkg Packard; But I passed.

HH56 good find I wonder of the durability of it and if it can run multiple items on it?

I am also thinking of A/C now that I moved to Las Vegas and after this last summer (Brutal)I may spend some time in the junk yard,finding all the mounting and accessories I may need for a 12v on the side to run multiple options.

Looking forward to your results on the trans blizpack I hope it all works out well!!

Thank you JD I have been looking for this chart for a while now....

Hi I have ran across this blog trying to find my engine
# M 40 1990
I now have my mothers 1954 packard Cavalier That should have a 327 and dose have a 327 head but not sure on the block, I have never known it to be changed in the 45ys it has been in the family.
I have timing issues with it as my father did in the past; to have the valve open and close to their near stated readings I have to have the cam timing gear 180Deg off of the timing mark of the crank set mark ( I have been up and down with this) and have the near deg reading of 4deg ATDC when the #8 exgaust valve just closes as stated in the service manual and it will start and run but it is off!
I strongly believe I may have the wrong cam in it, I just want to make sure the block is that of the 327. It does have the date of 4-1-54 on the pass side block.

Any help would be great!!!
