Started the hydroboost mod on my friends 69' 300.

All spark plug changes from the bottom?

Just curious,

Is this to compensate for a big cam?

[T1 Woodywagon]

no, I change them from the top.

 

[T1 Woodywagon]

Yes, I am doing the mod to take the vaccum booster out of the equation. All the old stuff will be for sale.

This is very interesting. What is the source for the hydro boost module??

A lot of work that an electric vacuum pump could have avoided IMHO.

Kevin did you look at the before pictures ? The electric vacuum pump is right in front of your face.

 

[twostick]

So other than that pump being rather unsightly and probably noisy, was there another reason for a more complex system?

My pump took up very little space and only required a hose and 12V source to operate.

Similar to the above.

I've been doing various mod upgrades to this car for 20+ years, this is just the next one concerning the brakes. The noise of the pump is a non issue, the car has 3" exhaust and solenoid exhaust cut outs which are open 99% of the time.

I like to see threads with different solutions for making these cars better. Thank you for posting.

Is there a way to put a 15 second video in this thread ?

 

[CBODY67]

Link to a YouTube video can work, I believe.

Sorry I should have said from my Iphone. I'm not super computer tech savy.

Saturday morning update, finished the new pushrod modification for the booster, now its adjustable.

 

[T1 Woodywagon]

Update, starting to test fit everything into place. Ordered the P.S. pump bracket last week,hopefully it shoes up next week.

I'd never heard of this thing before so I had to look it up, very interesting. I notice on the Hydratech site they don't have a kit for the C-body. Which kit did you use here?

 

[T1 Woodywagon]

I went to a local auto wrecker and pulled everything off a 2000 gmc duramax, I got the booster,master cylinder,all the hydraulic lines and power steering pump for $150, but I'm making new lines at my work and putting AN fittings in the booster, also I flipped the booster upside down for more clearance, and all the lines will go from the bottom now.

 

[WissaMan]

Oh wow, cool. Nice work! I'll be really interested in hearing about how the brake action is once you get it all together and working

Looking at this project, I first wonder....Why?
Since I see a former vacuum pump set up, I presume it because of the engine combination was not making sufficient vacuum to run accessories?
