When boring & honing the AMC/Chrysler inline 6 generation of engines that most of us use (4.0,4.2,4.5,4.6 & 4.7 litres)a torque/honing plate needs to be used due to the flexible nature of the cylinder block. If not the engine is likely to be an oil burner and will loose some HP. This piece of kit is a very rare beast in the UK and will cost several hundred pounds to make correctly. I can now hire this to anyone who may need it, for a modest sum of £10/day and a £500 deposit to cover any loss or damage. shipping is extra. Please give me a call for more details. 07971 142928 John
