No luck so far on a 318... or brake assembly. :(
i got the manifolds off and drained oil in motor. lots of clumpy stuff coming out..
also gotta look for a set of 14" wheels.
If all you need is the 318, check out Pick 'n Pull in Dallas. http://www.picknpull.com There are three locations, prices are decent, and if the one you get is bad, they'll swap for thirty days. They have wheelbarrows and a-frames with hoists you can use to get your prize out of the car and up to the checkout area. Lots are gravel paved and most cars are off the ground.
Remember that the cast cranks were not machined for pilot bushings unless the car came with a manual transmission.
You have two options:
Have the crank on the 318 machined for a pilot bushing. I recommend this course of action.
Use the forged crank from your 273. No problem swapping as long as lightweight rods are maintained.
The south location has a 70 Dart in it that ought to be good for brakes. It may even be a 318 car which would give you the 90º oil filter adapter. I can check this weekend if it stays dry.
I also have a set of 5, 14 x 4½ on a 4-inch bolt pattern. The biggest tire I'd put on them is a 195/70-14.
