ok - i bought a hemi brake booster from newcombs
with his k frame the brake booster clears the hemi
Valve cover but it would be impossible to put a spark plug in the last cylinder with removing the
power brake booster ... is this normal? i have seen stock applications and it looks like a straight
shot- i am unable to contact phil -any help in that area would be nice

Are you using the correct mounting bracket?

As Snoopy posted. Are you using all the correct hemi mounting brackets?
Here is a picture of what everything looks like.

i added this picture
what i bought was a ebody power brake booster
tell me what you think

It looks like the right mounting bracket.

Here is a picture of Dave's (ECS) car.

looks like dave has a mile clearance to change that plug but when i look at other hemi ebody pictures it looks real tight -

Can you take an overhead shot looking down?

While your application looks tight, Hemi valve cover/booster clearance can vari somewhat in a non stock application using repro K frames, aftermarket mounts, repro brake booster brackets, etc, etc, small variances all add up to alter the clearances,....here's a pic of a former customers 71 B body, basically the same K frame, firewall as an E body,....this customers car utilizes a stock (non Hemi) K frame, Shcumacher mounts, crate 472, Dayclona repro Hemi brake booster assy. brackets, etc,....the number 7 plug is very tight, but can be changed out by using a universal joint on top of the sparkplug socket, followed by a short extension (very short), and by dropping in the socket w/U joint then adding the extension, then clicking on the rachet, you can loosen or install the plug,....installing the plug tower wire/rubber cap assy, is a little tricky too, with the black rubber boot slid off the plastic wire tower, and the spark plug wire clip/insulator end pushed as far as it goes into the plastic wire tower, the tower/plug clip end/insulator should just squeek by the booster into the plug tube, then slide the rubber boot along the wire into position once the wire tower/plug end are "clicked" onto the plug, just reverse the procedure to remove it,.....it can be tight, just keep cool, and "think" out the plug/wire install

Greg,...when I look at this photo, If I was doing the install, it appears you could loose the thick booster spacers, if you've looked at, or worked on enough offset Hemi boosters you'll see that the washers vari greatly in thickness's, if so equipped?, they usually are, as the booster rods will vari "somewhat" in installed length, hence the need for the varying thick washers, to "tune" the installs rear rod clearance againsts the firewall plate/interference fit,....you appear to have enough clearance to loose them, the only thing that matters is that the booster's rod and pivot linkage that attach to it doesn't contact the firewall re-inforcement plate in it's installed and operational state, because if it did it will put a residual drag/engagement on the front brakes,....plus you have a soft white foam gasket where the bracket attaches to firewall re-inforcement plate where the pedal rod travels thru,...it should be a sheetmetal plate that retains the pedal rod boot/grommet, with 2 tangs that fold over between the 4 lower studs to retain the pedal rod boot/grommet to the back of the booster bracket assy as it's installed on the firewall,.....loosing that white gasket will assure metal to metal contact bolting the assy in place, I think that's why your assy appears to angle donward towards the valve cover, the foam gasket between the booster offset bracket and firewall re-inforcement plate is allowing it, no matter how tight you bolted it,....I think these small changes would give you some additional room,...every bit helps

Mike

Greg if you look at member Snoopy's factory exploded display photo you'll see the sheetmetal tanged plate that I mentioned,...I also see a gasket #5-31-12 shown, but I've never seen one on a car, like you have installed, the white foam gasket that you have behind the main firewall re-inforcment plate to body gasket, should be more than enough to seal installment holes,.....here's a pic of my reproduction brackets, the sheetmetal plate with tangs (unfolded in pic) helps retain the 2 halves together, plus sandwiches the pedal rod boot/grommet to the main firewall re-inforcement plate, hope this helps

if it was not a major consideration regarding factory look, how well do the Bendix aftermarket boosters and brackets fit/work?

Steve if you are interested in "correctness" as far as looks,...Member Dr Diff here on Moparts makes offset booster bracket/assys that utilize the "standard" bendex dual diaphram booster that has the 5/16 rear studs,....the "standard" B/C body Bendix boosters have smaller studs, and different spacing than "HEMI" Bendix boosters

Thanks Mike

sorry not entending to threadjack

it is a wild looking piece of apparatus! was more so along the lines of the variables mentioned with non hemi k fames and mounts etc and also noticed this has slotted holes in the mount.

thanks for the other option
