MK3 1300 Economy Engine

Does anyone know how Ford restricted BHP on the MK3 1300 economy tuned xflow that was used from Feb 76?

 

Cheers

Looking at the manual all i can see is differant dizzy and carb settings, differant jets and accelorator pump strokes, the only other listed differance is the engine code ?

So swapping out the carb should remove the restriction and take it back to the standard tuned 1300?

If the engine code is different then surely there must be more to it than just carb / dizzy? Maybe different cam profiles on the camshaft, or different compression ratio?

The code refered to the state of tune, as said to best of my knowledge it was carb & dizzy related.

Would a Weber 34 ICH be a straight swap for the 1300 Xflow?

[sheffieldcortinacentre 749]

That's the single choke one if memory serves. Then yes.

I always thought the HC logo on the xflow was for high compression? Or did it mean something else?

If you don't want the original carb after swapping for the Weber I'll buy it

I'll keep you in mind, not sure when I'll be doing though.

i had one of these in the 80s,i replaced carb with a twin choke from a 1300e.ran almost as good as a 1600 ohv.

[sheffieldcortinacentre 749]

Yes hc means high compressìon, but the eng codes refer to more than compression ratio.

Also after all these years the rocker cover or just the sticker may have Been replaced.

 

A mk5 high compression engine with a vv carb as the eng code "LC" for example.

[wolfrace 116]

Yhea but would the high compression be to do with the head/pistons or block or does the head gasket increase this as I'm guessing they wouldn't say high compression if they'd just tweeked the carb and timing?

Interesting! Think I'll have to do this at some point but prob go with the single choke.
