Can anyone tell me or show me with a picture if a standard-size HEI will have enough space without hitting the firewall? Should I get the smaller diameter HEI instead? Also, would an HEI unit for a '70s Pontiac fit the 1964 389? :dontknow:

Thanks!

It should work, I've seen it on GTO's of that vintage.

Here is a good read on conversion (which includes a link to a converted '65 GTO);
