High all got a 1600 to replace the wheezy 1300 to go in my mk1, and have 5 speed to go in it too.
As the cars a manual will the 5 speed fit in the standard tunnel, dont really want to chop tunnel as its a tidy car ?
Anyone done this conversion in standard tunnel?
 

It will go straight in except for minor things like g/box mount to be modded, speedo cable from a TC/TF 4cyl Cortina and cutting the gearstick hole about 3in further back, thats about it..

Hi thanks for the info thats great, do have copy of classic ford with it in somewhere was just unsure of standard tunnel size. Do you have any info on the blocks needed to move gearbox? ido have gearbox crossmember from sierra also. Do i need single piece prop?
Thanks for any info

Its hard to say as Escort has 3 or 4 different g/box mounts, mk1, late mk1, mk1 auto, mk2 / auto.
 Best to bolt it to the motor and check how the mount sits, then work out what needs doing. ie mk1 early auto mount with 5spd is a 15mm spacer and re-drill mounting holes forward approx 20mm.
 Regarding the propshaft, if yours is a late (74+) its fine or source a mk2 1600 single piece.

Sorry to piggyback off someone else's thread, but when converting from a 4spd standard box to a 5spd Sierra box, do you use the same bellhousing from the 4spd?

yes
