BROADSPEED UPDATE # 5
Powerunit is complete (was actually built a few years ago) and has been fitted to the body shell to get bonnet clearance correct.
* 1293cc
* Original ARDEN (not reproduction) alloy 8 port cylinder head (unmodified)
* 10.25-1, 266 Camshaft, 1.3 Rockers,
* "SpecialTuning" Lite flywheel assembly, orange diaphragm
* MK I "333" transmission
* EN40 MK I crank/ Balanced bottom end
* Re-curved MK I distributor
Recently all ancillaries were added and the engine put on the engine Dyno. We used a very short inlet and weber trumpet to squeeze under the bonnet which ultimately hurt our figures. But we still reached the 100HP and more importantly 100 ft pounds of torque. Very happy!
