Clifford 6=8 intake and dual carb problems

Guys, I purchased the dual car setup and while installing, the rear carb impacts my brake booster. To make it work, I would have to either change or eliminate the booster or lower the engine a few inches. First off, I can modify the motor mounts but is there a limit to how low the engine should be set? I would imagine the drive line angle cant be compromised too much. I have 4-6" of spring lift and 37" tires. Second, I have a rear disc conversion so I need good vacuum to stop those big tires. Is there a smaller, narrower booster or is a vacuum pump an option?

This is a 4.6 stroker in an '82 Scrambler

Someone has probably already solved this problem. A body lift would give more room. I don't like tall body lifts (3") but a 1" I like. Maybe that and a custom air cleaner might work.

Hydroboost eliminates the diaphragm and should give you all the room you'd need. Likely a good choice anyway with rear discs and 37s.

Yes, but hydroboost also typically puts the nitrogen accumulator right where he's having problems too. Not all of them do, but just something to be aware of before sinking money as hydroboost typically isn't cheap.

Most hydroboost units can be clocked to any angle. Mounting it upside down will put the nitrogen accumulator completely out of the way.

Crockodotsky, I put a 2003 Chevy 2500 setup on the 258 in my J10. I used the Chevy pump (with the Jeep V-belt pulley), hydroboost unit, and all the stock chevy power steering lines. Got everything cheaply from the same vehicle. I used this ebay mounting plate to attach it to the firewall. The same seller has one for a CJ, but it requires welding.

While physically possible, I disagree with that because clocking them upside down would put the pressure fittings to the bottom making it potentially more difficult to bleed the air out.

Guys, thanks for the tips on hydroboost. I think that's the best way to move forward with this build. I learned a bit about these systems recently when the PS pump went bad on my 2004 1500 Suburban and I lost brakes. Anyone have ideas on which year and model would work best for an '82 Scrambler? The PS pump is the easy part as they look just like the one off my burb except for the extra hose barbs. I'm sure there are lots of hydroboost parts available from ebay or local parts yards

The Chevy Astro van hydro boost was/is the typical system used in CJ's.
Here's a link from my archives:


There are some updates since I saved it.
