Thanks for the reply Donovan!
I looks like I got it sorted out. I had to slot the bolt holes on both motor mounts, which allowed the motor to rotate some. I also had to elongate the holes in the frame mounts, which then gave just enough additional rotation to get the motor to sit square. As viewed from above, before the mods, the motor was not just situated off-set, it at a diagonal - as in this situation | / |
The G-force crossmember fits perfectly, so it may have been at an angle with the Sprint 6 installed.
I just test fit the Doug's headers, and they seem to fit as designed. That suggests to me that the motor IS properly square.
Crazy that I had to modify both the engine and frame mounts. I have to wonder if the parts tolorances are THAT sloppy, or if the car itself has a tweaked frame.
