Weber 48 DCOE
JacksAvon - 15/8/21 at 01:00 PM

Hi all,

I have inherited a 2lt Zetec black top, fitted with weber 48 dcoe carbs

I am told it is/was a race engine.
Fitted with those huge carbs, what BHP can I expect.
I am guessing some cam and valving has gone on.
I dont have the time to strip it yet, just after some rough guides/experience

Any clues please?

Having a look at the Dunnell web site
and option 3 it says 212-223bhp*

it also says

*Using 45 DCOE carburettors. Additional power is available with larger chokes, but with a loss of idle quality and low speed torque. Piston pockets may be required for valve clearance

When I went from carbs to injection I actually lost a bit of mid-range power (few bhp) due to the chokes being bigger on the Atpower throttle bodies and the flow speed being lower.

This is the list of what option 3 is.

I had the piston pockets

Thanks all, a bit clearer now.

Will call the engine builders, Connaught engines, in the morning
