Smaller brake booster
 
1 Attachment(s)
I thought I was going to have a problem with fitment but didn't want to cross that road until it was a problem for sure. My booster fits but doesn't allow the removal of the valve cover. I am running the tall Chevrolet big block covers and my motor is solid lift so the covers will have to come off for setting valves once a year. What are you guys running for smaller booster that's budget minded?

Hydro boost would give you more room, and you wouldn't have to be concerned about engine vacuum issues and great braking performance.

A 7 inch diameter dual diaphragm booster will give you lots of room. Don't know what cam you're running but Stainless Steel Brakes has a vacuum pump if your vacuum pressure is below 14 in. That's what I run.

Thanks guys, I'll look into those options. That 572 sure is pretty!

I just picked one of these up a few weeks ago. Haven't had time to install it yet though! Got the brackets and rods with it.:chevy:

I just ran into this same problem on my big block swap. What are the part numbers for the 7" brake boosters?

OR, will the brake booster from a corvette work??

Running the smaller boosters really cleans up the compartment. The only problem like stated above is if the cams not providing enough vacuum to operate properly. Ebay n most of the booster manufactures have plenty to choice from. On my stockish 350 works well with the smaller version.
