Engine Replacement

My original 1300cc engine that was fitted with 1600cc pistons, barrels and cylinder heads developed a large oil leak from the flywheel oil seal in October 2012 and had a large amount of end float on the crankshaft, as the engine had done 95000 miles since 1972 without a bottom end rebuild it was time to replace it.
I decided to get a VW Heritage 1600cc engine, my tinware was blasted and powder coated and improvements made to the manifold / carburettor heating for better cold / winter running.

Venturi ring fitted as used on US fuel injected engine fan shrouds to improve air flow through the fan

Original 1972 cylinder tin with cooling vanes to direct air correctly over cylinder head

New "Hoover bit" missing from original engine, it blocks the gap in front of the oil cooler in the fan shroud

Original 1972 thermostat flaps fitted into fan shroud to ensure correct air flow, warm up and engine temperature control

Original manifold ends machined to support Weber 32/36 DFEV full heat manifold centre section

New engine in position, it is easier to fit without the manifold and dynamo fitted.
Exhausts, manifold, Weber and dynamo refitted ready for first engine run and cam break in
My solutions to getting as much heat in to the manifold as possible using VW original design ideas and parts:
1: 10mm hole drilled in pipe from manifold and blanked off heat riser from No 2 cylinder, so only heating from No 4 cylinder heat riser.
2: Original VW Beetle hot air feed to back of K&N air filter, also crankcase vent feeding in to base of filter.
3: Original thermostat and flaps fitted to allow quicker engine warm up, the thermostat only works with the full tinware fitted.
4: Full custom made tinware under cylinders on both sides of engine fixed to engine cage to replicate the original set up. This ensures the cylinder barrels and heads heat up correctly and evenly top to bottom. 
Metal gaskets used between cylinder heads and manifold end pipes to allow heat to rise into the castings.
Oil temperature sender fitted to spare blanking plate on new engine instead of using dipstick sender
Rev counter and oil pressure gauge added to monitor new engine also fuel pump / ignition cut off switch added
