hello i am new here and wondering if anyone could help me with my problem i am having. i have a 88 dodge ram shortbox i am currently putting a Chrysler 400 big block in it. i have it in with the proper motor mounts, oil pan ect.. the problem i seem to be having is the break booster, mine is simply too big . i know you can buy a smaller one off the net. as well as everything, is there a car or year of truck that would have came with a smaller brake booster, i have access to a junkyard with a variety of mopars. if all else fails i could go to manual brakes. if anyone has tackled this engine swap and could throw me some pointers that would be great. thanks.
