Welcome to FABO from SoCal. You're going to have fun here. What kind of A-body are you searching for and what are your build plans when you find it? Inquiring minds want to know.
In response to ocdart, the ultimate plan would be to put a 440 in the car. I have some experience with that motor. I am not looking for a drag car; if I was, a 400 would be a better choice. I would probably recreate something that a 60's guy would have done. I would put a 4 speed behind it also, with an 8 3/4 in the rear. That'll give me the option to change the gears out if I want to really lay a good time down at the track.
