Yet another LS1/LS6/SLP Intake Question:
Can't seem to find the information I'm looking for, so I gotta check with you guys.
Facts: GM Cast PN 12560688 (LS1 part number), EGR hole, flat bottom.
Is this an LS6 intake (possibly a SLP)? If so, why would SLP use a LS1 intake part number, add EGR, and sell as a LS6?
Thanks!
MJ
