Thread: Super Comp outlet locations?

  1. #1

    Default Super Comp outlet locations?

    Kind of an odd question, but I currently have Super Comp #4108 in my '73 GTO, and am moving that 455 over to a '68 Firebird, which would use Super Comp #4107. I would also like to transfer my X-mid pipe assembly to the new car. Is it a reasonable expectation that both sets of headers (for a Pontiac 455) will have the same exit locations, particularly the width, which would keep me from having to modify the X-mid pipe? Thank you!

    The floor plans are different. The '68 is basically a NOVA (Nova, Omega, Ventura, Apollo). So the '73 is the wider/longer GM version. The heater & A/C boxes are different too. I do believe the transmission crossmembers are the same, but I might be wrong. This will dictate the width.
