brake over boosted

I have a 72 f-100 that was origanally a manual 4 wheel drum, I used a booster and master cyl from a 70 truck with a 390 (mine is a 302) now everything works but I am way over boosted (very touchy brakes) any ideas?

I suspect you have a MS for disk brakes which deliver a lot more volume. If you did not convert to disk brakes you need to use your original master cylinder. Which will not connect to a power brake booster requires a different MS.

thanks this is possible , I've also found a great site that suggested I have my brake rod in the wrong position giving to much leverage.
Check out this site, lots and lots of brake info (Pirate Jacks Brakes) one of the best out there.
thanks again
