i have an a14 bottom end i no longer need,so it's for sale.it has a balanced crank,79 mm pistons from a japanese company,a rollmaster precision timing chain & gears,a 70 degree factory cam,shot peened conrods,& is precision balanced.it was assembled by arthur jackson at the road & rally centre here in sydney,& all machining was done by wilkins performance at seven hills.the motor had 10.5- 1 compression with a small chambered head & was quite strong.it still turns quite freely.i want about $500 dollars for it,which might seem a bit much,but the pistons alone cost $1000.i could probably find a cylinder head if necessary.
