Yes, I had to cut forward of the pinch weld. I lost some time trying to figure out why since I assumed that with the motor forward I wouldn’t have to cut as much. But I think Holley didn’t just move the motor forward, they moved it up about 3/4” as well.
Also, I have the big cast aluminum bell which doesn’t help any. The QuickTime bell is shorter at the top of the trans and might make a decent difference.
I have enough room for my factory heater box, but not sure about a factory AC box. I documented some of the things earlier that setting the motor up did. Not saying they were absolutely necessary, but the stuff Holley built around that motor location would make it tough to lower it.
I have in the back of my mind that if I like the Hemi enough, I could see swapping the motor into my ‘74 with the A833OD using the Holley stuff and doing more of an edgier build and using different mounts and headers to set the motor back and down for better weight. But that is just an idea and for now I am ok with the compromises.
