nuget Posted August 30, 2012 Share Posted August 30, 2012 So Im about to get a 1600 711m crossflow engine to go into my mk1 in the next month or so. Ive been told this is a pretty straight forward conversion but there are a couple of things that would seem like a problem to me. Firstly, Ive been told that the 711m is a little longer than the precross 1500 kent so therefore some modification to the radiator mount/support is needed? -Will the 711m bolt straight onto the standard 4sp column shift box? -Will i need to change the exhaust to the otherside because Im pretty sure crossflow exhausts are on the drivers side? -Do I need to modify the throttle body to suit the Mk1? I'd really appreciate it if anyone who's done this before can shed some light Churr Quote Link to comment Share on other sites More sharing options...

tedidesign Posted August 30, 2012 Share Posted August 30, 2012 crossflow exhaust is on the passenger side, no problems radiator support stays the same as the blocks are the same length. a 711m is about 10 mm wider across the block where the engine mounts bolt on, thus the mounts are a bit different. I fabed up a x member like an escort world cup one to suit have a look on http://www.cortina-mk1classifieds.com/forum cheers TED Quote Link to comment Share on other sites More sharing options...
nuget Posted August 30, 2012 Author Share Posted August 30, 2012 Hey Ted i also heard that I have to get a certain type of sump (off a mk2 cortina i think?) to clear the x member? cheers Quote Link to comment Share on other sites More sharing options...
tedidesign Posted August 31, 2012 Share Posted August 31, 2012 oh yeah forgot about that. The escort sump is a rear bowl, whereas the mk1 /mk2 Cortina needs a front bowl sump. You will need to get a sump of a mk2 cortina, as the rear oil seal on the 711m block is a lip type seal, whereas the early cortinas used a rope seal. Much better arrangemant anyway cheers Ted Quote Link to comment Share on other sites More sharing options...
