As part of this Triumph TR4 race preparation service we look after every part of a race car. That includes engines and gearboxes. The black and red Triumph TR4 of Dave Griffiths has been undergoing some winter prep ahead of the 2019 season. The engine has been freshly rebuilt with a brand new cylinder head from a new iron casting. Additionally, we’ve changed the camshaft profile to make another jump in power. We will fit a new clutch plate before the engine is mated to the freshly rebuilt gearbox. Finally, the whole unit will be fitted in the car before a rolling road session to dial in the new head and camshaft. The car has it’s first test booked at Brands Hatch on March 1st. Fingers crossed for a dry day.
