Old Hilborn SB Chevy fit Cadillac?

Anyone know if really old 3-piece (1957) Hilborn SBC Injection setup will fit a Cadillac?
The guy I got it from said the top could be used on Caddy... I have attached a few pictures to help the experts.

Specs:
1 -11/16" throttle bores
1 -7/8" & 7"distance between stack bolt centers
4-1/2" distances between intake bolt holes

Anyone have a Hilborn for Caddy that they can measure?

Thanks,
Andy

Is this what you are looking to find out?

 

Thanks Michael (yougsspeeed) for digging out your hilborn and taking measurements over the phone!

The measurements between the Chevy & Caddy manifolds are off by ~3/8" or so. The next step I took was to buy a intake gasket set for a 1959 Caddy and see how they lined up... Well they don't. The ports are the same size but the length between the ports is different. I have attached a couple pictures to show the difference.

Does anyone know if the spread on Caddy ports changed in the earlier 50s motors?

Thanks again,
Andy

 

Looks like they meant for a guy to cut the pieces apart and bolt 4 separate pieces to the Caddy?

The power of the HAMB! TRULY AMAZING!

 

I picked up one of these a couple years ago, mostly because I thought it was cool.
Is this a rare piece?
