What are the numbers stamped into the top of the block? They will be located on a machined surface on the front of the block just in front of the intake manifold, viewed from the top. Example: D55-3-3911C (de-coded this number is a Dodge, 1955, and the number of the engine produced.) It is a 55 Dodge 270 cu in. Super Red Ram. I just bought this one out of an old truck at a local wreckers and paid 750.00 Canadian for. The wrecker sells old mopar, especially hemi so he knows what it is worth. If you de-code the hemi I could phone and ask him what he thinks is a fair price.
I also had a 354 that was rusted and seized and soaked it in W-D40 for 6 months and it unseized.
