I have the camaro elbow. Was feelin fancy some years back, and didn’t wanna look at a hockey puck anymore. Memory sorta foggy now, but I think I had to poke a hole for the Opti-spark harness, or the IAT. But it worked great.
That car was totaled 3ish years ago, got the motor sitting in the garage. One of these years it’s going to replace my current LO3
