Flipping the OEM Motor mounts ?

[gimmy 64]

put my motor in yesterday. my valve covers are 4in. tall. original motor mount holes. barely fit .had to message my fire wall abit .now I have about 1/4 in. clearance from valve cover. I don't think 4 1/2 will work. I tried reversing the motor mount stands and they really didn't fit very good . top holes kinda of matched but not really?if you move to the front holes I don't think you will have a problem with the long pump because this what I have. lots of room but I don't think you can run a fan shroud.
