You would probably pull a few more horsys out of the engine if you inject it. I know 2l pintos gain 10bhp when injected.

Injected improves just about everything, id keep the carb though, some twin 45's mate and your little kent will be roaring all the way to 8000 rpm [:x)]

Sorry to intrude but i was making 125hp with a stock engine. I was running a fuel injection and turbo though. But internally its stock:head,cam,rods,crank,main bearing caps,valves evrything basically and she was bloody reliable...till i got the hunger for more power[%]

so im thinking
single side draught 45 mm weber
kent 234 performance kit
ported head (how much not sure match porting mybe??)
duplex timing chain
stock bottom end
exhaust 2.25/exstractors
electric dizzy
lightend flywheel (again not to sure on how much want a little torque but with the heavy pistons dont no what a good comprimise would be?)
thats what i was thing this is all going on a 711m 1600 with low kays around the 50,000km ive been told and looks it so all thoughts welcome ohh and what revs would i be looking at max 6500??
cheers luke
sounds very similar to what i have planned, but i already have; single 45 on lynx manifold (rekitting as we speak) kent 224 (some machining req'd) elec ign duplex chain drive stock bottom end 2.5" exhaust already unleaded head stock flywheel high flow oil pump dont know how much i will get, but definately more than current :) same thing with the install - but my issue is time. i can put it all together myself, but i dont have the time... or i can pay someone to do it, but i dont have a ball-park of cost... let me know (roughly) what your quote is... if you dont mind :)

Trade the BCF2 for a 234 or even a 244. I wish I had gone 244 now.
The later cams have 1mm more lift and slightly less duration and will make power to 6,500-ish

the reason i choose the bcf2 is i dont have to get the pistons fly cut, do ya reckon it would make a big diffrence?

On the road it won't matter much. I ran a BCF2 years ago in the same spec and it was a good cam, plenty of power and torque.
The '2' series cams are just a newer design and probably a bit more efficient.

I used JP engineering special 83.5mm pistons with 1300 size crowns and valve relief cut extra wide and deep,cant remember the part number but can find it for you and this set up uses std head gasket and results in just under 1700cc ultra reliable kent.
Also the flat kent head is capable of much larger valves than GT size
talk to Trick heads or superflow heads both in Sydney, and ask them about single valve springs, worked for me up to 8k very regularly.
Use a 1300 6 bolt flywheel, much lighter than 1600.
change your rocker posts to solid block type(smcka might have them in stock)or at least cast type,the alloy ones will break.
PS there should be an old post on here with part numbers, around the time smcka was building his engine.

oh thanks a heap for that, as for pistons i no all the poms bore them out to 83.5 or 85mm if ther game but to be onest dont see the point for the few extra cc's rather have all the extra life in the block as for the head yeah i agree 100% but the main factor with that was i have a flate ported head with gt size vavles and double vavle srpings allready fitted if this doesnt prove to be anygood ill go from there. thanks for the heaps up about the post will be getting them done for sure if there a common isue i was under the impression the flywheels where the same waight im not exspert though, do you no what the 6 bolt flywheels came out of as my 1300 mk2 only has a 3 bolt worried me considering they where only 5/16 bolts lol thanks a heap cheers luke

FWIW. This may already be common knowledge as I am fairly new to the Escort scene.
Subaru valves out of the 1800 pushrod engine are worth considering and if you find an old motor then also very cheap. They are a nicely made valve and dimensions are;
Inlet - 41.4mm Stem dia - 8mm Lgth 109mm
Exh - 35mm Stem dia - 8mm lgth 109 (exh can be machined down a smidge)
This combination takes you fairly close to max without moving valve guides.
Stem dia and over-all lgth you should find very close to OE xflow dimensions. You can also use the Ford OE collet's/retainers (or the subaru double spring retainer can be also be used but needs some taken off the OD. Unfortunately the tapered double springs from the Subi don't fit -to big). Add some lash caps if you wish which should give improved geometry in the rocker setup/angles (ie. maximise the efficiency and lift of any given cam profile) with the std post height and pushrod lgth(assuming you aren't achieving the same objective with post heights and pushrod lgths).
cheers Ian
