Depending on the tune, 500 hp or more at the tires easy.

Like said above,over 500 rwhp even through a C4 with a loose convertor. Dyno numbers wont be where it shines,the track will be.

just depends on how much boost and how big of balls you have....

700 shouldn't be a problem at all.....

Actual hp no problem for that setup.....seeing that much on a dyno with a loose convertor and c4 probably not.
If you want to "see" high dyno numbers stick a 5/6 speed in it. If you want to run the number at the track don't worry about the dyno numbers,just use it for the tuning aspect.

HED did a 347 stock block t-trim a couple years ago and on the engine dyno I think it did 920hp for about 5 pulls them BOOM!!! Just wondering if you are using a dart block why not 363?

HED has also built a stock bottom end 302 T76 turbo combo that made 800 + at the tires on race gas. A blower is a lot rougher on and more power robbing than a turbo though. As far as a converter, you don't want a real loose converter. Not with a power adder (blower). I'd recommend calling your converter manufacturer and giving them- weight of car with driver, engine specs, and gearing. Then they can recommend the right converter. You may need to get it tuned and then have the converter restalled depending. There is a guy up here in NC named Greg Slack that makes some of the best converters out there. He's very knowledgable and been doing it a long time. I'll see if I can get his number for ya.
