V8 swaps into British roadsters are nothing new, but this 1974 MG BGT on Hemmings goes well past a drop-in conversion. The seller says he spent 10 years restoring and modifying it, finishing in summer 2025, and replaced nearly everything mechanical: a blueprinted 4.6-liter Land Rover V8, a T-5 five-speed, a Ford 9-inch axle, and entirely new suspension and brakes. The bid stood at $32,000 with six bids when we checked, and the auction had about three days left.
A Factory Idea, Finished the Hard Way
The V8 MGB has factory precedent. MG built the MGB GT V8 from 1973 to 1976, roughly 2,600 cars with Rover's 3.5-liter aluminum V8, and the Hemmings listing notes those were right-hand drive and never sold in the United States. This U.S.-market BGT follows the same recipe with a bigger engine. It is the same family of aluminum V8 that powered everything from the Land Rover Series III to the Range Rover.
The Engine and Drivetrain
According to the listing, the 4.6-liter overhead-valve V8 was machined, blueprinted and modified by HorsePower Research, using components from D&D Fabrications, a Buick-Rover V8 specialist. It has a Crower Level III camshaft, Holley Sniper EFI on an Edelbrock Performer intake, Holley HyperSpark ignition and an aluminum radiator. Black powder-coated RV8 headers exit through the fender wings into a custom dual exhaust.
Power goes through a BorgWarner T-5 five-speed mounted with a D&D conversion kit, which includes a McLeod hydraulic throwout bearing, then to a Fast Cars Ford 9-inch rear axle with a limited-slip differential and 3.25:1 gears. The listing does not publish a horsepower figure, so anyone bidding should ask for a dyno sheet rather than guess.
Suspension, Brakes and Body
The chassis work is what separates this MG from a typical swap. The front uses Fast Cars tubular control arms with adjustable coilovers, and the rear is a custom three-link setup, also on adjustable coilovers. Wilwood four-wheel disc brakes sit behind 17-inch Cosmis Racing Mogul MR-II wheels wearing 225/45 Bridgestone Potenza Sport A/S tires.
The body went through a bare-metal rotisserie restoration. Sebring-style flares cover the wider wheels, the rubber bumpers were deleted with their mounting points filled, and a custom front lower valance and hood sharpen the nose. The paint is Sherwin-Williams Ultra 7000 in California Sage Metallic, which the seller lists as an Aston Martin color.
Inside, Mazda Miata bucket seats were re-trimmed in leather with Alcantara inserts, and the dash is wrapped in Alcantara with Speedhut gauges. Vintage Air climate control feeds vents built into the center stack and dash ends, a hidden Bluetooth head unit runs JL Audio speakers in the footwells, and an Advance Auto Wire harness ties the upgrades together.
What Is Documented and What Is Not
Several details are backed by paperwork. The listing's photos include early-stage shots of the bare body shell, and the seller says the car comes with build records, a photo book of the project and Blackstone oil analysis reports. The title is a clean Texas title in the seller's name, and the seller reports no current needs. The odometer reads 2,687 miles and is marked TMU, meaning true mileage unknown.
Everything else, including the "essentially a brand-new car" description and the component list, comes from the seller, and Hemmings states it has not verified the listing's accuracy. A pre-purchase inspection is worth the trouble on a build this custom, and our guide on whether to buy a modified classic car covers what to check.
Why It Stands Out
Putting a V8 in an MGB is the easy headline. Reworking the axle, rear suspension, brakes, wheel arches and cabin to match is the hard part, and that is where this car earns attention. It also continues a long British tradition of dropping American-style V8 power into a small roadster, the idea behind the Sunbeam Tiger. If you prefer modern power in an old shell, we also covered a 1966 Ford Bronco with a Coyote V8 on the same marketplace.
