Question for you Corvette/Chevy guys:

Can you give me a rough idea of what engine this might be? What year?

the infamous, LT1 swap.

edit: there's a reason you see so many of them. I saw one in a BMW 3 series.

Being unencumbered by knowledge, I had to google "opti spark".

I guess it was a space saving measure since it was in the Corvette and Camaro primarily. Those engine bays are tight to put it lightly. It was also in the big body RWD Impala SS/Caprice/Roadmaster

how much more water does that push than the old system? why did they change it?

@flamesarewicked

got it, space saving. thanks.
I’m sure the water pump flows just the same as a non opti spark.. just the location of the distributor being behind it saved space where as a conventional one would be sticking up in the back against the firewall of a Camaro or Corvette.. talk about a pain in the ass lol small block Mopars were the same way.. distributor in the back.
