Paul Anderson’s Triumph TR4A engine is now complete. Built to a fast road specification with 89mm pistons, 270 degree camshaft, lightened flywheel and a ported and polished cylinder head. It should go very well.
TR4A engine rebuild complete
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.
