It started out as a 1958 Triumph T110 bottom end, complete but in need of a total rebuild. The cases were stripped and bead blasted, with all threads checked and repaired where necessary. A late sixties two piece crankshaft from a TR6C with the lighter flywheel was used, with reground journals to first undersize, polished conrods and all new bearings.
Later NOS nitrided E3134 camshafts were used with all new bushings, and R cam followers running in Morgo tappet blocks. The cylinder is a Morgo 750cc kit and topped off with an early twin carb 9 stud head. 
The alloy pushrod tubes join the late style blocks to the earlier head, and house lightweight performance pushrods.
The rocker boxes house lightened dural tappet adjusters and solid spacers instead of the original springs to reduce friction. They are joined by an original finned Webco oil rail.
Other goodies include a finned sump plate complete with drain plug, timing cover with tachometer drive and oil seal conversion and a Morgo rotary oil pump to keep the whole lot lubricated. 
The magneto is a Lucas Competition model (K2FC) but with all internals removed. They will be replaced with a Boyer electronic ignition unit which will be fitted further down the line. 
Still needed - Oil pressure release valve, intake manifolds, finned rockerbox caps and a dynamo blanking plug to switch to later alternator electrics.
