long block
English edit
Etymology edit
From the larger size of the engine block assembly compared to a short block.
Noun edit
long block (plural long blocks)
- (automotive) An engine subassembly that consists of the assembled short block, plus the crankshaft, cylinder head, camshaft (usually), and valve train.
Usage notes edit
Not the same as big block, which refers to the physical size of an engine rather than the completeness of the subassembly.
