i have a 44 mb l134 that machine shop said its got to many cracks, so a rebuilde in tx may have one for 1000 includes shipping to ca. a place in ark will have in a few weeks one that is turn key, just drop it in but price may be around 8000

or so and they run it several      times. if i can get the head from tx the rebuild will be with block and all about 5000, a big diff but the expensive on was pre run. yours am sure is sold. did you have all the work done for you. any advice. had lots of trouble with over-heating, did everthing and more to fix it but ???
