My name is Dick Boyer I am the director of sales and marketing for PBM performance Parts. I just wanted to clear up a few miss leading posts regarding our new PBM iron block. We at PBM strive to provide the engine builder with good quality engine parts and at no time would we knowingly sell something that had an issue in any way. So with all the allegations posted on this site I thought it best if you heard it from the people most resposible. We sent 3 blocks out to an independent metallurgical lab today to have a BHN test performed on them we sent a Bow tie GM block a Dart little M block and our new PBM iron block all of the blocks tested above 187 the PBM block tested 195. I also had a PBM block cut into sections to determine wall thickness and am sending a section of this block to an independent metallurgical lab to have a BHN test a rockwell test as well as a chemical analysis to determine the propertiies of the iron the block is made of the lab says this is the most accurate method. We here at PBM do not take lightly any idea that we would sell something that has issues of any type. If you have questions about this or any PBM products feel free to email me at
