73 nova transmisson leak

I replaced the standerd powerglide with a turbo 350. now it's leaking when it's not running i'm sure it leaks when it's running to but when it just sitting there it leaks a considerately amout of tranny fluid any idea's on what it might be? thanx

Usually whenever I have a transmission swap going on, I install a new front, rear seal and o-ring for the fill tube. I've even had tranny shops do it for a few bucks.

Have you narrowed it down to the front seal or rear for instance? Those are the most likely areas where you'll find a leak, make sure that the fill tube is all the way in and the o-ring is in place.
