Bernie Posey's 1979 MGB with 3.9L Rover V8

as published in BritishV8 Magazine, Volume XVII Issue 1, July 2009

Owner: Bernie Posey
City: Elyria OH
Model: MGB
Engine: Rover 3.9L V8
Conversion by: Jeff Foote and Bernie Posey

Engine: Rover 3.9L aluminum V8 with Edelbrock Performer 2198 dual-plane intake manifold and 390cfm Holley carburetor. Crower 232 camshaft. Buick distributor. (Note: to use the Buick/Delco-Remy distributor in lieu of a Rover/Lucas unit, the drive gear on the alternator which mates to the Rover camshaft gear was cut off and replaced.) Crane Fireball XR700 electronic ignition and Crane Fireball P591 coil. Fuel pressure regulator and fuel pressure gauge. D&D Fabrications swivel mount oil filter adapter. A Rover harmonic balancer was used, but with only one of its two original pulleys. The rear pulley was moved to the front, and for alignment a Buick 300 alternator bracket was used in combination with a double pulley on the alternator. A Buick 300 water pump was used, with an early Buick pulley shimmed outward for proper belt alignment.
Cooling: MGB tanks (reversed, and with oversized ports) installed on a 4-row "Super-Cool" core, about 2.5" longer than stock. A Spal electric fan (pulling) supplements the original MGB electric fans.
Exhaust: RV8-style headers into a homemade exhaust system with a single Thrush muffler.
Transmission: Tremec T5 (Ford style) with 0.63:1 fifth gear. 10.5" Camaro clutch. Henderson driveshaft.
Rear Axle: stock MGB.
Front Susp.: stock MGB.
Rear Susp.: stock MGB.
Brakes: stock MGB.
Wheels/Tires: Minator aluminum wheels with Goodyear "Allegra" 195/70R14 tires.
Electrical: 100 amp, one wire alternator. Relays added for cooling fan and headlights. The headlights are Euro Style from Victoria British with the blue halogen bulbs. (They are really bright.)
Instruments: stock MGB. (Tachometer modified to suit.)
Interior: Pontiac Fiero seats with headrest-mounted speakers, reupholstered in ("Mr.Mike's") leather.
Roll hoop with windblocker and LED third brake light.
Weight: stock MGB.
Completed: May 1998. (150,000 miles driven as of June 2009!)
Comments: This MGB V8 was built to be a dependable road car with modest but improved performance, which it certainly has been. It has been a very reliable car for the past eleven years. Iíve driven it to Phoenix, Florida, Nova Scotia, Minnesota, and many other places.

Several major changes have been made to the car since the initial conversion was completed. "Block hugger" four-into-one headers were originally used, but they cracked, and were replaced with "RV8 style" through-the-fenderwell four-into-one headers. The RV8 style headers provided improved clearance to the steering universal joint, which had previously been a concern. The original Rover tranmission has been replaced with a Ford-spec Tremec (new/aftermarket) transmission, and that's proven a huge improvement. A Ford 8" rear axle was temporarily installed, but the vendor who narrowed it didn't do a good job. The original MGB axle has been reinstalled for now. Eventually, a properly narrowed Ford 8" axle will be reinstalled.

Dual PCV hoses.
Formerly, the PCV system drew crankcase fumes through the manifold vacuum port on the carburetor.
Redirecting the hoses to the air cleaner (and its lower vacuum level) seems to have reduced oil consumption.
