Tops are identical as far as the fit and function. If they modified a ‘production’ xram, they only used the top 1/2”.
The differences are drastic other than the top 1/2” where the top plate mounts. The port layout is very similar to a Boss 302. ( I bought an original intake to compare ports ) The rad hose mount comes out the front and not on top. Drastically different.
I asked Jim if I could 3-D scan the intake on the silver car when he owned it. I considered trading some ZL-1 parts for the motor out of that car when Jim offered it to me. But we did not end up making a deal and he ended up buying my parts from me.
There was also an auction in Phila years ago that had a hemi head stup along with an original ZL-1 block if I recall. I was out of the country or I probably would have bought it.
