1965 MGB roadster - rolling again

Another project Ive not mentioned since last year, is the 1965 MGB roadster. After the body was painted, the underside was given several coats of a high quality stone guard, and the sills, doors and all the box sections were injected with copious amounts of cavity wax. It was then time to start rebuilding some mechanical parts to get the car back on its wheels. The rear axle and differential were fully rebuilt with all new bearings and seals, and refitted to the car with all new bushes and bolts. The front subframe was fully rebuilt in a similar manner, replacing any parts that were past there best, and anything good enough to re-use was thoroughly cleaned and painted.
With the car now rolling on a set of 'slave' wheels, the slightly nerve wracking job of fitting new stainless body trims was undertaken. The results are pleasing, and its certainly nice to see the 'B' looking more like a car again.
The most recent task has been the rebuilding of the engine. The engine being used is a later 5 bearing B series, with a few minor tweaks. As usual, everything was checked, and anything that needed to be replaced or machined was. The engine is bored +30 with new pistons, the crank was polished, all new bearings were fitted and the flywheel had a new ring gear fitted. The cylinder head has been mildly re-worked to improve breathing, and a fast road camshaft has been fitted along with new timing and rocker gear.

The next job is to rebuild the gearbox, and then both engine and gearbox can be fitted back into the car.
