    If you are going to play around with valve sizes or you want to change where the power occurs, you might find this interesting. Basically, you need to seriously look at the intake manifold with any EFI system.

    if your heads are off and the work hasnt been done yet PM guy hes got what ID call a mild 3.9 pushing an auto and hes happy with it so far.

    from memory some head work was done when we found the heads knackerd from toasting, he didnt get any manifold work done as $$$ was against him and had a new cam put in but I dont remember what profile he got at the end of the day.
