Piston and liner set, 78mm dome top
These are also suitable (and desirable) as replacements for the flat topped piston version used in H vans (H78 engine) with cross flow cylinder head (after 9/63) and provide a useful power increase. They are a direct fit replacement with no other changes required. These can also be used as a direct replacement in the H72 H van engine to take it from 1628cc to 1911cc, but some carburettor changes may also be required.
We have used this set in Traction Avant's and pre 9/63 H vans, but the cylinder head combustion chamber edge needs some machining to make clearance for the piston dome.
New life after 15 years
I bought an ex fire engine H van that has already been converted into a catering truck thinking that new fuel plugs and points would get it going...........two of the pistons were rusted into the bores but the neat thing about the design is that once the big ends are undone it all comes apart. Now unseized and with the new pistons and liners installed it runs. Brakes next and then the body rot - hours of pleasure......"
