$500 for 340 that's a gift around here. If you can find one in this are a 
  340 will run $750 and up. My buddy wants me to get a 360. Not sure about that 
  motor. Ford motors are easier to find than any AMC's. What kind of 400 was it 
  Ford or GM? they made both. Crate motors are too high. Around here crates 
  don't have the complete motor. I saw a sweet Cyclone on ebay it was a 
  convertible. I like the hideaway headlights on them.
Maybe i'll jog down 
  yonder Tennessee area. They have some nice yards down there.

    You can still find 340's relatively cheaply. I have sold 4 complete 340 
    motors for $500.00 - $600.00 in the last 6 months. You can buy new 340 
    blocks with extra webbing for alot cheaper than you can buy a similar 
    offering from Ford.I just put a stroked 400 (mopar) in a guy's 71 Gremlin.I 
    had plenty of clearance. You are right, a 440 may have some issues with the 
    brake master cylinder and you may not be able to run power steering. We had 
    tried to find him a 401 and didnt come across anything so he took the next 
    best thing.....There is a guy just down the road from me that put a Buick 
    455 in his Gremlin......looks great....I think I would rather have an 
    AMC motor in mine though.....429 is a good little motor. I bought a couple 
    of 70 Cyclones a couple of years ago. Both were 429's, 1 was a 4 spd. Wish I 
    would have kept them They would fry the tires.........eddie

      Maybe i'll try to snag a ford motor. Mopars are expensive especially 
      the motor I'd like to get (340). Back in the day (1980's) my brothers 
      friend put a 440 in his Gremlin.It fit, I bet it was tight. As far as 
      ford goes i'd probobly snag a 429. They are'nt as wide as a 440. My dad 
      had one in a 70 T-Bird. It had some balls to 
      it.

          find for a GM and they are cheaper too.
 
        
        that's not really true as finding a used 350 nowadays is getting 
        hard as many yards rip em out and sell em to South America.todays chevy 
        crate motors are about the same price as a Ford one.
