I used the white foam gasket that is inbetween the vac booster and firewall as a template to make the alum plate with. I also used 4 rather large bolts/nuts to bolt my plate to the firewall. which is not needed but all i had on hand at the time.

are you going roller or flat tappet? I used the hughes cam extention with one of the pro-gear t-chains they have. the whiplash roller cam is a short nose cam but are all very nice pieces for the $. I removed a lunati voodoo roller cam and went to the whiplash. they both have specs that are almost identical but the whiplash has the choppy idle. voodoo smooth as stock. both make a 318 run like it should in a truck...not too much but just enuff to know it is not stock. I used comp 901-16 spring with both voodoo & whiplash roller cams. 7 yrs on the voodoo and 8 months on the whiplash. no problems so far, and I run the poop out of them. myself I like it, it drives like a stock cam on light throttle,but you deff feel the torque and throttle responce from off idle to redline with it. it fit the bill for me, I wanted the performance of the voodoo I had,but wanted the choppy idle and drivabilty of the whiplash in a daily drive street truck. it moves my 85 stepside along ok,will spin the tires with a 2.76 gear,sweet spot is about 60 mph and knocks back a good 18 mpg, sounds nasty idling thru town, smooths righ out around 1800 rpms and pulls strong when you nail it WOT. I run a q-jet on a LD4B intake with headers/duels stock 727 high stall non lock up TC. with a 2.76 gear 235/75/15 tire. I am going to a 3.55 gear with a nv4500 5 speed in the stepside, that should be real fun with the whiplash. on a side note.. my 88-318 with 360 heads worked great with the voodoo cam and would be just as good as the whiplash in it. I have a 2nd 318/349 stroker going together with the 360 heads, I have the RPM non-airgap intake for it with a whiplash roller cam for a 360 going in it. also have a whiplash flat tappet going in my 88-440 truck. did I mention the whiplash is a killer street cam?

I hate to bring this old thread back to life but I hit a snag on my truck that I can't find the answer to and hoping someone knows. I put the small diameter, big block brake booster on and it rides hard against the MP valve cover. I decided to go manual brakes using the 1983 master cylinder. I fabbed a cover plate from .063 stainless and need to know if this is the pushrod that will work. Nowhere can I find any dimensions for it. http://chucker54.stores.yahoo.net/mopeadbrrodp.htmlMopar Performance Adjustable Brake Rod Pushrod Item# MOPP4510640 $53.95 . Product Description This handy threaded brake rod is great when you adapt different master cylinders on Chrysler or Tube Chassis cars.

The swap is easy. Any hotrodder can figure it out. Hardest part is picking the right master for pedal feel based on caliper/cylinder size.
That said, I'm running a whiplash on my 5.9. 222/228, 107 LSA installed at 104. Idles at 8".
My power brakes work fine. Check your booster for leaks

Thanks but you missed the point of my post a little bit.

no, not really. you said you were contemplating a swap due to low vacuum. so, are you thinking about the swap, or are you absolutely sure that you want to do the swap, and if so, is it because you want to do the swap, or because you think you don't have the vacuum needed to keep your booster happy?
what does your cam idle at? I told you mine idles at 8" and I have plenty of vacuum for power brakes, and even if I stand there and pump the pedal over and over, I don't use up the vacuum in the booster.
you used about 2 sentences in your post, so with that little of detail, it's hard to tell what you want to do or why you're doing it.
That said, it's your ride, it only has to make you happy. DO what you want to do with it. I was simply offering the other side of the story to your "contemplation" since you hadn't made up your mind yet. sure you can do the swap. nothing wrong with that. but, you may not HAVE to do the swap if you didn't want to.
