Here's mine.
Connaught Competition Engines built 1689cc xflow
Standard 1600 block, decked and rebored
1300 +90 lightweight pistons
New piston rings
Balanced crankshaft
Ex formula ford big valve head
Full port and polish on the head
Valve seats uprated for unleaded
New valves, valve guides, stem seals
New uprated single valve springs
Steel rockers and rocker shaft
Duplex timing chain and sprockets
Lightened flywheel
Stage 1 AP clutch
Piper 285 camshaft
Weber twin 40 DCOES
Long ram inlet manifold
105speed Mass style exhaust manifold
Custom single box exhaust by Pipecraft
Engine set up by BD Engineering, and dyno'd before the 105speed manifold was fitted at 135 bhp at 6200rpm, although the power graph was still climbing when he let off.
We are planning to get them to re dyno it, ideally to 6800 or thereabouts and we are expecting probably 145-150bhp
Would just like to mention a special thanks to young Sam at Connaughts, built the engine himself and we couldn't be happier with it.
