'71 Duster 440 or 360? Pros and cons
It may be bored already but the cylinder walls still have visible cross-hatching so it would only need a hone job. From what people are saying in this thread it's almost as if nobody thinks a 440 is a worthwhile swap. I just found a BB 727 that I could buy for $100....
I like Bob Shingler's advice. Buy the 727, collect the parts, buy a drag car for that stuff, but drive the heck out of the 360 car in the meanwhile.
I had one that I had a big block in it and put 11,000 miles on it in the 11 years that I owned it (which is very sad, it was broken most of the time). And I've got another that I have 20,000 miles on it in the last 5 years (weekend driving, this car is amazingly reliable, almost no options, small block). They handle very close (both had/have upgraded suspension), the big block was only a little faster off the line, good for burning tires, but I put posi and bigger tires on the small block car, thus they are about the same. The small block can get 18mpg, the other had a best of 13mpg. For daily driving on the street, there's no real difference to me except mpg. I never went drag racing, and never did track racing. I only recently got a 360 small block myself. I'm very excited about having a motor that handles like a small block, but with a bunch more torque. When I blow my 360, I'm going to port the heck out of the heads, aluminum intake, good pistons, valves, medium aggresive cam, building it for as much torque as possible. (spin the tires, but cruise at all other speeds :p)
