Finished a 3.1L build a few months back. LD28/VO7 crankshaft, late(9mm) L24 rods with ARP bolts, 89mm KA24 pistons with slight dish. L28 N42 block and N42 head, ARP head studs.
Rebello hot street camshaft, Isky valve springs and retainers, OEM adjustable camshaft gear, lightweight steel flywheel, Performance Products SFI spec harmonic damper.
OEM high volume oil pump, Mallory Unilite distributor and coil, triple Weber 45 DCOE carbs, Cannon intake manifold, ceramic coated Pacestetter header, etc.
Block was clearanced for the LD28 crankshaft and bored using a torque plate, head received porting and smoothing work, intake manifold match ported, engine balanced to within 1 gram.
.075" Cometic MLS head gasket used for approx. 9.6 to 1 compression ratio, custom carb heat shield, OEM fuel rail modified to add 3rd fuel outlet, valve cover and crankcase vented to catch tank with breather and drain, etc.
2 1/2" exhaust system, OEM Exedy/Daikin 240mm clutch set, 280ZX close ratio 5 speed, 300ZX Turbo R200 3.70 limited slip differential, etc.
The engine had it's final tune with about 1,500 miles on it when initial timing was reset and the final set of advanced timing curve springs were installed in the distributor.
The engine is in a 73 240Z and I tried to make the install look almost like it was stock except for the Weber carbs, but as soon as the engine is fired up you know it is definitely not stock.
The engine revs to 6,500 RPM quickly and the car will make 90 MPH in 3rd gear like right now. A lot of fun to drive. The engine was not an inexpensive proposition but well worth it.
