For Sale:

1977 MGB Roadster (refitted with factory LH-Type Overdrive)
Purchased in 1995 by current owner. Stored in weatherproof shipping container 2005-2017.

Located in San Luis Obispo County, California; registered in Alaska where I reside. Original California vehicle. I'm usually in the county for several days each month, when I can show and demonstrate the vehicle. Currently garaged and driven occasionally.

Engine:

Odometer reset to zero when engine block was rebuilt in 1998; currently: ~37,500 miles.

Cylinder head rebuilt November 1997; 10,000 miles driven before engine block rebuilt.

Both the cylinder head and short-block assemblies were rebuilt by Alternative Performance, San Luis Obispo, California, a well-regarded and highly recommended automotive machine shop at the time, specializing in gasoline engine rebuilding.

Cylinder head work included:
—Hardened valve seats (for unleaded fuel), new exhaust valves, new guides and seals; re-surfaced.
—Head was installed with all new studs and nuts during first reinstallation, reused when reassembled (w/new copper head gasket) after block rebuild.

Oil and filter replaced at 3,000 mile maximum intervals, Castrol 20/50.
Oil consumption: remains nil to minimal, i.e., normal during 2,500-3,000 mile intervals.
Oil spectro-analysis performed in 2017 on oil from 2005 in storage. High lead detected due to occasional use of 100LL avgas (100 octane leaded aviation fuel) blended with premium unleaded. Since most recent oil change no avgas has been used, only premium 91. The next analysis is expected to be normal and will be available for inspection.

Engine Block Rebuild, January 1999 included:

—New Oil Pump.
—New Water Pump.
—New Timing sprockets and Double-Row Chain.
—All New Bearings.
—Block was die-penetrant tested and resurfaced.
—Replaced camshaft with rebuilt serviceable unit.
—New Pistons.
—Flywheel resurfaced, new starter ring gear installed.
—All new cold-galvanized freeze plugs (brass not available).
—Permatex Aviation Gasket Compound used where appropriate.
—Copper head gasket (new in both cases) and and torqued to specification.
—All new Engine Mounts.
—Break-in procedure per Alternative Performance recommendation performed, including: pure (distilled) water coolant for head gasket seating first 500 miles, 2000 RPM first 20 minutes for camshaft break-in.

—4-row oil cooler (new) installed prior to engine rebuild.
—Radiator boiled at time of rebuild, cooling system always serviced with 50/50 glycol and distilled water. Fluid remains clean and oil-free. Hoses and belt in good condition.
—A failed electric radiator fan was replaced with an aftermarket 12” suction fan, augmented by the remaining stock fan.

Ignition System:

Crane Cams XR700 electronic advance enhancing the original distributor assembly.

Intake system:

—Weber DGV carburetor installed. Original Zenith Stromberg carburetor and combined intake-exhaust manifold are included off-vehicle.

Exhaust system:

—Pre-1975 cast exhaust header.
—Straight-to-glasspack resonator/muffler, reasonably quiet, tight, no rust.

Fuel System:

Fuel tank has never leaked or had any problems; the sender unit (and seal) and the fuel pump (and associated rubber hosing) was replaced with the original-model SU pump at some time between 2000 and 2004. Apparently, I failed to record these items in the maintenance record. Other rubber fuel hoses are in good condition, all having been replaced at other times, as deemed needed.

Drivetrain (2004):

—Stock Type LH Overdrive Transmission (used, unknown mileage) installed in July 2004 during suspension rebuild project. Input shaft seal and cover gasket renewed. Overdrive filter screen renewed and new overdrive control and backup light switches installed. It has performed as designed and with no problems.
—Clutch (heavy duty) installed during 1999 engine rebuild retained. All new high grade fasteners, new clutch pivot lever bushing; clutch and components had about 19,300 miles accumulated since engine rebuild at time of suspension and transmission project.
—Roller Bearing type throw-out bearing (i.e., not the standard carbon friction type) installed with clutch replacement during engine rebuild.
—Rear axle bearings replaced and driveshaft tubes-to-differential housing re-welded by a shop contracted by British Sportscars, San Luis Obispo, California.
—Used serviceable propeller shaft sized for OD transmission with new U-joints installed; all new high-strength fasteners utilized.
—Speedometer serviced and calibrated for OD transmission; odometer reset to indicate mileage since engine block rebuild. Odometer read approximately 94,000 miles at that time, presumably accurate since new in 1977. New speedometer cable.

Suspension Rebuild (2004):

—All flexible buffers/bushings and mount pads replaced with premium “Prothane" components. Crucially, this includes the front axle assembly (“front-end assembly”) crossmember beam-to-chassis attachments. The crossmember was removed, disassembled, cleaned and repainted with zinc-rich primer and finished in black before reassembling with shocks, axles, brakes, steering gear, etc.
—Refurbished (4) stock Armstrong shock absorbers installed.
—Front and rear springs replaced with new 1” lower than stock.
—Swaybar mounting bushings and links replaced.
—New Tie-Rod Ends.
—All wheel/axle bearings renewed.
—Steering arm gaiters replaced.
—Brakes: all rotors, drums, caliper-piston assemblies, drum brake piston assemblies, shoes and hydraulic flex-hoses renewed. Rubbing of brake drums against backing plates is minimal and only during harsh maneuvering at higher speeds; much improved over condition prior to project commencement.
—Rebound straps intact, replaced twice since purchase in 1995.

—New tires installed May 2017; 4 Toyo Extensa A/S 185-65-14. As a result of being a lower profile than the previous 185-70-14 set, the speedometer is off by 4-5 MPH. In hindsight, I should have kept the previous size for that reason and for probably better fuel mileage and possibly better handling. They look good, though. The spare is original to the car; original jack and lug wrench kit.

Interior (the would-be next project):

—Original upholstery (Autumn Leaf), door and window seals and carpeting are due for replacement; driver’s seat-cushion cover is deteriorated.
—Robbins zippered rear-light hood (i.e., convertible top) was replaced in 1996, and still in serviceable and waterproof condition despite neat and durable repairs following break-in when the vinyl fabric was cut in two places in 1997 (it’s not a good idea to lock the doors).
—Dashboard exhibits a crack on top, typical, in need of an overlay repair.
—Passive-restraint shoulder harness seatbelts newly installed in 2017.
—Inexpensive AM-FM receiver and CD player and stereo speakers. Nothing special, i.e., of no interest to thieves.
—Aftermarket cruise control, functional.
—Engine block cockpit heat control valve replaced summer 2017.

Body:
—Paint (Tahiti Blue) in good condition, with some recent chipping damage to the boot lid and bonnet in need of touchup after a horse or horses attempted to chew on the body while my back was turned as the car was being moved from its safe long-term storage shipping-container through a pasture (horses are not to be trusted around valuable objects, as it turns out).

As a horse guy you speak the truth on that :-). Probably the most detailed history/restorations documentation I've see outside of some 'trailer queens" that just go to shows to win a trophy.
