RT Posted June 21, 2005 Share Posted June 21, 2005 look for the casting numbers on the side of the block.. if it the number ends in AA then its a 1100-1300 if it ends in BA then its a 1600.. Another way to check is look where the water pump is and the 1600 will have about 10mm more space before the head.. The 711M is the casting number and is generally preferred because it's apparently slightly thicker of the batches.. Quote Link to comment Share on other sites More sharing options...
Toucan Posted June 21, 2005 Share Posted June 21, 2005 A pre-cross flow has both the intake manifold and the exhaust manifold coming out of the same side of the head. A cross flow has the intake ports on one side and the exhaust ones on the opposite side, so they are quite easy to tell apart. I'd also look at the option of putting a 2L pinto in, they are the sohc 2l that come in lots of cortinas and the higher spec escorts, it would be a bit more work to put in but probably worth it,. But if you want a simple swap then yes a 1600 cross flow will be piece of cake, and 711M is the number cast onto the side of the 1600 block's I think.

Guest mark09 Posted June 21, 2005 Share Posted June 21, 2005 ok, how about telling if its a sport/gt or not as my hand book says that the 1600 has 75hp at 5000prm and the gt has 93hp at 5400rpm? both being 1600cc Quote Link to comment Share on other sites More sharing options...
RT Posted June 21, 2005 Share Posted June 21, 2005 not sure about external signs... but internally the GT xflow has a chambered head and bigger ports I think. So if you can take the head off... Quote Link to comment Share on other sites More sharing options...
Guest mark09 Posted June 21, 2005 Share Posted June 21, 2005 would the exaust outlet holes be the same size on both of them or could i just measure that? Quote Link to comment Share on other sites More sharing options...
Pushrod Posted June 21, 2005 Share Posted June 21, 2005 Just a note prexflows in a Mk2 tina were either 1100 of 1500cc and only the early ones had prxflows id say stick with the xflow and yes if you can get a 711m block better followers and mains and a few other things also some say a later casting number is better such as t19 if you are pplanning on a bore increase Quote Link to comment Share on other sites More sharing options...
Guest Demonmk2 Posted June 21, 2005 Share Posted June 21, 2005 haha whoops wrong thread, anyway the 1600 xflow has got 84hp not 90odd it has in the ford's manual thingy Quote Link to comment Share on other sites More sharing options...
Guest Jamezuu Posted June 21, 2005 Share Posted June 21, 2005 gt 1600 has a different inlet manifold, more curved and bigger where carb flange is. Also has factory extractors. Quote Link to comment Share on other sites More sharing options...

Jerm Posted June 22, 2005 Share Posted June 22, 2005 Only the very early 1600 Xflows have chambered heads.. most are flat, with bigger valves, GT cam grind and as said before better followers... the ghia ones are the same. and yeah i think gt's had weber carbs and the exhaust manis are extractors.

Pushrod Posted June 22, 2005 Share Posted June 22, 2005 You can also get a standard head chambered and run a sligthly dommed piston if you want to got for mega power Quote Link to comment Share on other sites More sharing options...
Jerm Posted June 22, 2005 Share Posted June 22, 2005 Yeah me and the guy that heled me build my engine toyed with the idea of flat topped pistons with a chambered head but would haev to run av gas.. wasn't to keen on that Quote Link to comment Share on other sites More sharing options...
Pushrod Posted June 22, 2005 Share Posted June 22, 2005 You could build a mega engine like that for the sport since it's just sitting there Quote Link to comment Share on other sites More sharing options...
atropine Posted June 22, 2005 Share Posted June 22, 2005 also.. i was under the imporession that 711m blocks are mk2, 681m (or somthing like that..?) is mk1.... Quote Link to comment Share on other sites More sharing options...
RT Posted June 23, 2005 Share Posted June 23, 2005 ok I dug up some info from my extensive archives The 711M block came about in 1970. It features a stiffer crankcase and stronger main bearing caprs. They're square shouldered as opposed to the earlier round type. They have a more modered screw in oil filter type of pump rather than the canister and element version like the MKII Gotina. The head face is also flat, while the block carries the corresponding pistons to go with it. These are the ones that are most suited to high-power tuning. You will find 711's in both 1300 & 1600 in every Ford car from then on. Eventually phased out for the pinto and cvh engines. But it still lives on today, called the Endura, a version is found in the Ka and the Fiesta and Valencia versions. Like I said previously, the best way of determining a 1600 is in the cast stamp. The number will end in BA. ie. 711M-6015-B-A, the 1100/1300 will be AA. Quote Link to comment Share on other sites More sharing options...
