Building a fast road engine for a TR4A

Last week we began rebuilding a TR4A engine for Paul Anderson. He is restoring the vehicle but decided to bring the engine to us. We will be fitting 89mm pistons and liners, a slightly hotter camshaft and doing a little work on the cylinder head. The increase in capacity should make the biggest difference with a flowed head and camshaft to give it that little bit extra. So far the block has been acid dipped and is awaiting the new liners. The crankshaft has been ground and is now getting balanced along with the flywheel, clutch and conrods.
