• BBF Longblocks



    ZSR Big Block Ford longblocks are a full custom build, nothing mass produced or machined/built before being ordered. We have many options available so please contact us for your needs. Like all of our engines, everything is done in-house and the longblock will arrive to you assembled and painted the color of your choice. These can be built for anything from 700hp to 2000hp+

    Why do a ZSR longblock instead of a shortblock? The advantage to going with one of our longblocks over a shortblock is that it takes the guess work out of the engine work for the end user. We set the rocker geometry, determine pushrod length, check piston to valve clearance, determine and use the proper thickness and bore diameter head gaskets, etc. If we do the oil pan as well we set the pickup clearance and install everything for a leak-free result. All of these steps are absolutely critical and it can be a gamble doing it at home for some customers.
