Hi just a few questions to bounce of any body . Are twin 40's any good on a 2l pinto car will be driven most week days and Sunday occasionally at track days and hill climbs . Any advise would be good

There was a comparision between the 32/36 and twin 40's on a KENT motor in a recent issue of Classic Ford Mag. 15 extra ponies with the DCOE's.

In my experience that while 45s if matched to cam, compression, ingition, etc when jetted and choked correctly will give you more power overall, 40s give better bottom end and mid range response.
 
Best suggestion I could make would be decide on where you want your power range and what you are prepared to put up with as a daily driver, then select the cam to suit your preferred range, calculate your ideal dynamic compression ratio and ign requirements to suit and finally decide on your induction set up.
 
Many will suggest going the singe DCD route for simmilar overall power to dual 40s and better fuel economy, but the throttle response and note from well tuned dual carbs are hard to beat. If you decide on dual DOCEs/IDFs/etc don't even consider anything smaller than 34mm chokes though, otherwide you will strangle the poor thing.
 

Hay thanks guys yea low to mid range power would be what I'm after for a Every day car Im only thinking goin this way as I have a manifold and a pair of twin 40's sitting around . Any suggestions on a cam ??

I had a 2litre in my old mk1 which i ran 40's and it ran really well. Im pretty sure it was a Kent FR32 cam i had in it from memory (engine had porting and decent compression etc).
I think this was on the limit of the 40's with this cam and may have benefited from the jump to 45's if you were being pedantic, but to be honest it ran fine. Had heaps of torque and power. With a power band from about 2200 - 6500 i used to cut it off at.
 

Thanks evobda2 think I will carry on with the twin 40 idea will need bigger chokes tho as it only has 32's in it

You could always sell your 40's and spend half the money on a bike carb setup and pocket the change!
 
They are easier to tune than webbers and at half the price are pretty hard to beat.

Hay Matt I had thought of going that way but wasn't sure what bike carbs to use and where to sorce them from . I'd be correct in thinking I have to make a manifold ?? You've got my interest now . Do you have more info on this conversion ??

Check the link out - http://www.classic-ford.org/cfp/tm.aspx?m=51809&high=
 
I got a guy in Adelaide to make the manifold for me.  But you can get them from the UK delivered for around $250.00 AUD.  You can get a set of carbs from UK or USA delivered for around $200.  So for about $500 you are up and running and they sound awesome.
 
Any questions let me know.
 
Cheers,

I am also looking at a carb upgrade from the weber 32... This bike carb setup looks tops, very interested, has anyone got any spares or bits to put this together? Let me know...
The other I was looking at on ebay is the single delorto 40.
 
Cheers,
