The MGB V8, built for 1973, was fitted with the Rover V8 all alloy engine. And because the power output of the 3.5 litre V8 at 137bhp was lower than the earlier MGC engine, there was nothing required in the way of chassis strengthening, and better still this light V8 engine had a similar weight to the standard MGB 4 cylinder B series. Putting the V8 into the MGB had been done earlier by Ken Costello, with engines tuned for much higher outputs, but BL decided to stick with the 137bhp standard tune as being adequate for the showroom. Production of the MGB V8 went on to 1976, in the rubber bumper era.

MGB GT V8 tyre size was originally 175R14, a size that is available sometimes at an inflated price. The ideal tyre size fitted by everyone today is the 185/70VR14 size, the Blockley being a high speed rated, steel belt construction and period correct.
