Get your Lotus twin cam running again with this brand-new engine block from Ford Racing! Using original blueprints and modern techniques perfected over many years casting high-performance engine blocks, Ford has improved the Kent-based Lotus engine block for strength and reliability. This block is a direct replacement for the original later 116E/120E and 701M 5-main blocks, right down to the engine mounting bosses on each side.
Freeze plugs and camshaft (jackshaft) bearings are already installed. Oil gallery plugs and bellhousing dowels are included but not installed. Includes main bearing caps, main bearing cap bolts, and specification sheet. Accepts standard size main bearings, sold separately. "Medium deck" height of 7.80" provides a little extra material for decking.
Note 1: The cylinders are left slightly undersize (81.97mm / 3.227" nominal) so that you can hone them to your own specifications. This means that final machining is required before use. This block can safely be bored out to a maximum of 83.5mm (1593cc with the original 72.7mm 1558cc crank). All other machining steps have been done.
Note 2: A provision for an oil dipstick has been added just in front of the rear main bearing. If you do not use a dipstick, you will need to plug this hole. Dry sump lubrication systems will also need our 15/16" Expansion Plug (Part No. 161-61-.9375, sold separately) to plug the crankcase breather port above the fuel pump.
Note 3: The center main bearing web on these blocks is machined to accept the full-circle 2.0L Ford (SOHC Pinto) Thrust Washers. This provides more stability and resistance to strong clutch release springs.
