Twin Cam Engine
Posted: Sun May 27, 2018 9:23 am
Hello All
I am a brand new member of the group and am refreshing my memory from long ago of owning Lotus cars!!
Would any of the knowledgeable people assist with the following.
I intend to re build a Lotus twin cam engine using the crossflow 711M tall block (probably my AX block). By preference I would leave the block at its maximum original height (undecked) as this helps to preserve the structural integrity and general strength within the block. An added advantage would obviously be the increase in cc which I also wish to achieve.
My intention I think is to use an 82mm stroke steel crank (if I can find one), in conjunction with the appropriate length rods and forged pistons. Am I correct in thinking that because the cylinder head would be higher on the engine, due to a full height undecked block, would I need an adjustment to the brass tensioner pivot? If so is there such a thing available anywhere to purchase or if not how I would I achieve the relevant modification on a standard size tensioner pivot?
Also, because the block would remain at full height (undecked) would I need a timing chain even longer than the extended 122 link chain?
Thank you in advance for any helpful advice or guidance you can offer from the obviously knowledgable people on the site.
