Weber 48 DCOE

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
http://www.dunnellengines.com/zetec_carb_optionkits.php
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
