sholdowa Posted February 12, 2007 Share Posted February 12, 2007 681f block is the predecessor to the 711m, found in Mk.2 cortinas and the early Mk.1's. This *could* be a legendary 'L' block - the ones that were modded for the original 1558 twincam, although it's more likely to have been out of a 1600E or similar. You need to check the deck height for that. Just call me a sad bastard Quote Link to comment Share on other sites More sharing options...
L0WMK2 Posted February 12, 2007 Share Posted February 12, 2007 full code is 681F 6015DAwhat is it??? 681F 6015 The ‘L’ version of this block was the original fitment in MKII L/Cs and obviously takes the 3020E type b6 bolt L/C crank. Round main caps. Most will bore to 85mm if they have a low ‘T’ number. as this early crossflow unit used in 1600Es and 1600 GTs carries the same number as the MK II L/C but is easily http://www.lotus-cortina.com/library/block/blocks.htm Quote Link to comment Share on other sites More sharing options...

sholdowa Posted February 12, 2007 Share Posted February 12, 2007 haha so in other words its a 1600? Almost certainly. These blocks were all the same bore, and varying cranks were used to change the capacity. If it's *not* a 1600, then it could be worth lots! Is is a 4 or 6 bolt crank? Whatever, it's the best of the (usual) early 60's kent blocks, but not as good as a 711M. Quote Link to comment Share on other sites More sharing options...
