Intercooler and pipe size?

Interesting, I've seen them on both, I'd go before the carb hat, how big is your current blow off? If you wanted to run two you can wouldn't hurt. If you can just run the pump for the intercooler with key on, and it's up to you if you want to run just a loop circuit or use a ice box, if you go ice box can get one with a rule pump, these are awesome pumps lots of high hp cars runs these in their ice boxes.
