Hey guys, first off let me wish you all a Merry Christmas and Happy New Years. I have a lead on 2 poly 318's I am considering for my 46 Dodge pickup project. My question is what parts are still available and what are the ones I am going to have trouble finding. Are most of the parts interchangable with the magnum 318? I thought I read somewhere the lifters are different and not in production anymore. Lastly, can you use the same torque plate on the poly as with the magnum 318? My engine man will not touch anything without a plate. Thanks guys!
