You'll be fine but the 98.5 has the smaller bore lower IM if I recall. You'll just have to test fit them and visually examine the fit.

Otherwise, I don't see any faults with your Strap On plan.....




HA! Nice burn with the strap on!

Does the LIM from the non SVT 1999 have smaller bore than the 98.5 SVT LIM?? I was under the impression that the 1999 model year 2.5 duratec has one size LIM, SVT=NON SVT.

Also, is there a larger bore upper intake manifold in the 1999-2000 SVT model year?

Maybe I should ask a more direct question, instead of confusing everyone. What is the best UPPER AND LOWER intake manifold upgrade for a 1999.5 non-SVT contour with a returnless fuel system?

Thanks for all your help guys,
