stock HL510 engine, 227.45mm block deck

fully counter-weighted crank.  140-150hp w/ head work & induction upgrades easy... 180-200hp possible w/ $$$

Z20 1952 85 x 86 ~8.5:1 same dimensions as L20B, x-flow head, typically not regarded as a performance engine.  Block nearly identical L20B.
Z22 2188 87 x 92 ~8.5:1 stock 720 truck/200sx engine.  note long stroke.  Same external dimensions as L20B/Z20.  Z22 short block base for popular "L22" combo (Z22 block + L head).  
Z24 ? ? ? last Z series engine, only used in trucks.  Block is taller than L20B/Z22 and requires motor mount mods to fit under 510 hood.
