You're a bit beyond my normal realm - but in terms of basics - the PG is for lighter cars - under 2800lbs race weight is what I've always been told. So I'd think it would need mroe gear. But - before that I think the fuel system needs some work. I'd want -12 from sump to regulator and -10 from reg to carb if you're only filling through (2) inlets rather than (4). I don't know that two -8 can feed it that well considering the launch. Once the rest is worked out the convertor may be fine.
