Custom mechanical fan builder

To correct myself - the pulleys are over driven, but I'm not sure of the %, I mixed up the 30% number with something else. I agree i don't think the stat was the issue, but rather a poor pusher cooling system for a big motor.

Part #'s?

Like I said, 30% overdriven is still less than the factory AC ratio.

That's what I'm getting at. If it gets hot while cruising at a reasonable speed, the pusher fan isn't the issue and no fan replacement will fix it.

Right, but he didn't say what kind of driving he was doing so you can't assume what the problem is. Not enough info.

When does it get hot? Does it cool off if you pick up and maintain speed?

A pusher almost never works, but knowing whether you have a radiator/flow issue kinda helps establish whether the pulley system is worth keeping. At least that's my take..

Exactly, we need to know when it gets hot to diagnose whether it's fan or radiator or general cooling system. Like I said, not enough info to jump to conclusions.

A pusher can work if done right just like anything else. They generally don't work because somebody just slapped a pusher on to solve a cooling issue that wasn't a fan problem and are running a low CFM fan in combination with a mechanical, which the pusher lowering the cooling efficiency when the car is moving at speed. If run as a stand alone with a high enough CFM rating it can work just fine. Not my favorite, but totally workable.
