Details:

This is a 1974 BMW 3.0 CS with a new fuel-injected, 3700 Rally Engine.  This example has been restored and upgraded to become one of the best examples currently offered on the market. The car has undergone an extensive restoration including:

  • 3700 Rally Engine – A big bore (96mm) short stroke (86mm) gives these engines a rev-free nature and great bottom-end torque. The 8mm longer premium “H” Beam Rods improve the rod ratio (rod length divided by the stroke) for higher revving and reduced cylinder wear loading. These “H” Beam Rods weigh almost 200 grams lighter than the stock and are coupled to the crank with special coated Tri-Metal Rod Bearings. The lightweight but very strong pistons and rods reduce the reciprocating mass even more to 6 lbs. less than a stock M30 engine. Besides spooling up quicker, this lighter reciprocating mass reduces vibration at high RPMs and adds longevity. If you enjoy Driver’s School Events, Auto crossing or just hard highway/street driving, then this engine really delivers.
    • The Rally M30 Engines produces 305hp with a fuel injection syst. and 
    • the following mechanical upgrades:
    • Machined and hand ported head with 18% flow increase.
    • Surface Turbulence treatment to the Head reduces detonation, virtually eliminates head cracking, results in greater fuel economy and lower emissions.
    • Sport Camshaft that offers good idle and drivability.
    • Sport/Rally Head: improved head flow with Surface Turbulence Valves and Sport Camshaft
    • Single Row Timing Chain for increased life and less parasitic loss.
    • Rocker Arms: inspected and 30% stronger than stock.
    • Lightweight “Bee Hive” Valve Springs & Retainers to reduce Valve Train load.
    • Manganese Bronze Valve Guides for tighter valve stem – to guide clearance and extended guide life.
    • Moly Top rings and 3-piece Oil Rings for good oil control & long life.
    • Rally Engines have lighter 143mm “H” Beam Rods.
    • Rally Engines have special Heavy Duty Tri-Metal rod bearings.
    • Blue Printed Oil Pump with bronze pressure relief valve sleeve. For greater oil pump life and improved oil volume.
    • Dual Chamber Sprayer Bar to the #1 Exhaust Lobe from wearing out.
  • Subframe:
    • Removed, disassembled, repaired, painted.
  • Upgraded Bilstein shocks.
  • Upgraded drive shaft.
  • New re-upholstered seats.
