***Update: Our HYD Roller Longblocks now come with USA-Made Johnson Lifters****
ZSR Dart-Based 9.5" Longblocks. Full custom builds, no mass produced engines. Cylinder heads done in-house; not "shelf" items. Whether you want to make 500hp or 2000hp, we can get a package together to meet your goals. Name-brand, quality parts ONLY.
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.
