Barely any Brakes

I didn't build the 340 for power. It is basically a stock rebuild. Its only a street car for cruising.

Thanks for the ignorant, un helpful post to this thread.

Hey man, we're not trying to come off as A-Holes/D!cks. We're only trying to help you. A Front disc brake upgrade is (be it a SBP or BBP) will greatly decease braking distance vs drums. Again, I'm trying to come off as being mean, but I want you to think about this.

Let's say you're crusing along doing the speed limit (its a very nice day), when a little kid jumps out infront of you chasing the ball that went into the street. Its a full blown panic stop moment, one system will have a shorter stopping distance, the other a longer stopping distance.
Or to put it another way, one system will have your heart in your throat and instant rage at the parents for not watching their child. The other will have your car seriously damaged, the police arresting you, insurance company fighting you on getting the car fixed, two grieving parents who are suing the unholy **** out of you, a crap load of attorney fees, and probably a lot of bills from a therapist that you've been seeing to help you get over the kid you hit/killed with your car.
God help you if hit a kid or adult with any type of disability.

Again, we're not trying to be A-Holes here, we're only trying to help. In my case, my car (1970 Duster) came with front wheel drum brakes, 9" if I remember correctly, just like yours. The very first thing I did to that car was swap in a front disc brake system.
