[QUOTE="Hotrodtractor, post: 121185, member: 25"] Yes I still recommend a block filler - it greatly stiffens the bottom end and has not proven to be any issues with a partial fill and day to day use including towing. I also have to say there are better block fillers out there than "Hardblock" take a look at some of the two part polymer block fillers that almost resemble epoxy. As the engine block heats and cools and flexes under power cement will break away from the walls and then you will just have a block with cement in it. The polymer fills adhere to the block and you will rip chunks out of the block before it lets go - its a much stronger setup when finished. [/QUOTE]
