Just so you dont lose all hope in your 318.
This is my 320 with a stout rebuilt 2 liter.
Its putting out a easy 130bhp.
This is with the old 3.64 diff , its got a 3.91 now.
You have to accept that your car will never blow away Mustangs or
even 325's (not "i"s but "e"s all day long).

But you can kill smaller cars like Hondas and Neons.

If you like e-mail me for more M10 insight.

later,
Teaguer
