I don't have the part # on me, I don't think they are that expensive either. Crower makes billet rods and crank for the Zetec also.

Not as obscure as one might think It is a bit of info I require so I can build a zetec with a higher static compression ratio, among other modifications. Btw, I have been advised as to what the figure is. The zetec, in it's various forms is becoming a spec motorsport engine, eg,FF2000 Zetec championship. thanks for the interest. Mark.

Not a wealth of knowledge, I'm new to the motor. I am using a 96 contour Zetec in a vehicle that has a total weight of <1300Lb. I would like some more power as I am classed in a group of vehicles that have over 250 hp at my local road race track. The coefficient of drag of the car is in the 0.70 range , so my top end is nothing to write home about even though my 0-60 is in the low 5's. I was advised by an extremely reliable source on this board that the c/chamber vol is 47.7 cc. so I'm on my way to calculating how much shaving is required for various compression ratios. Mark.

I have seen one in person by my house and at first I was unsure what kind of lotus it was when I saw it. it was a nice looking car.. do you have any pictures of your car?
