I've just picked up my new engine for my '95 mondeo and am busy cleaning all the inlet system up etc.

I have noticed that the lower plenum port sizes are much smaller than the port on the head.

Is it worth me getting the lower plenum ports bored out?
and larger butterflies fitted in the secondaries?
Is there anything that can be done to the top plenum to improve flow?

i don't want to spend too much time or money on the engine yet but just do some basic tidying up.

Also, can anybody recommend somebodywho can do the work?

Any advice welcomed.

Cheers,

Paul

Thanks, mine is the early vacuum operated one, the step is about 3mm!! so I'll definitely blend them. I wonder if it is possible to modify the later larger ported one to take the vacuum system, that would save me some work.
