looking to see what brake booster i need for my 85 cougar putt'n a 577 in it heard a need a small one any clues? what ideas on the o.d of the difference anyone?? thanks
A 5.0 Mustang booster is a lot smaller than a stock thunderbird/cougar one, but I dunno if it'd clear a big block.
Can’t wait to see your car post some pics
Our cars are fox’s so anything done to stangs cane be done to ours.
Good luck
thanks one more will the master cylinder work or do i need a "stang" one i will get some pics up thanks again
Mark, a 1994-95 Mustang 5.0 brake booster (non-Hydroboost years) is skinnier and will work perfectly for what you're doing. Just need to redrill one mounting hole in the firewall. For the m/c, you still have the cast iron one. From 1987-on the m/c was aluminum with the plastic reservoir. It's up to you which one to go with, but as of right now your setup is 2-line (both front, rear) whereas the newer setup is 3-line (left front, right front, rear). It can be replumbed but then you couldn't use a line-lock as easily. You may be better off keeping what you have. If anything you could upgrade to a Crown Vic m/c, which holds more fluid.
ok i have the 2 line m/c with a line lock already installed so that one will work just have drill another mounting hole everything is the same bolt right up going to get one today thanks MIKE:cougarsmily:
will that booster work with tall valve covers? i have the p-51 heads with the roller rocker arms mike:cougarsmily:
Its going to be tight if it does. manual brake conversion is you friend.
