yes I run one. JW ultra-bell on mine, along with a JW flexplate. Those two parts are stout pieces. Pricey, but strong. No issues whatsoever. It's a simple deal. Cut the OE bellhousing off of the case and fit the JW onto the pump and bolt it down. Make sure to use loctite on the bolts. I also use a stock starter.
As for the trans itself, with as much power as you're planning on, I'd go with a 1.80 straight cut gear. Factory 1.76's are strong but at that power level (over 1000) they'll probably break eventually. Especially in a heavier door car. The lighter the car the less strain on the driveline components. dual ring servo, good band, good valve body and an overhaul and it's good to about 1000 HP if it's set up right....and Powerglides are REALLY easy to build. Are you going to use a transbrake? If so, it's a good idea to increase the number of clutches in the reverse pack to AT LEAST 5. 6-8 would be better and last longer. Some come with 3 from the factory, most are 4. I run 2 in a footbrake only setup. Just can't touch the throttle in reverse. But it has a little less drag. I also run a turbo spline input for more converter selection. I think the turbo splines are becoming the standard for powerglides these days. I also bought an aftermarket pump that was already machined for the input-it wasn't expensive ($125). Mine has held up great. About 800 passes with not even a fluid change, about 700 HP in a 2500 lb car. The 'glide was probably the best mod I have ever done. The C4 is a good transmission but the glide is faster and more consistent. More expensive too, but well worth it!
The only issue I ever had was one time I left the snap ring out of the reverse pack and when I'd put it in reverse, it'd lock the pack against the carrier--locking up the transmission. My own stupid mistake. Last weekend I ran it up on a transbrake a time or two in the pits and it rocked forward a little-but that is to be expected with only 2 clutches in the reverse pack. Converter went 6200 without the low chip. Datalog shows footbrake flash stall at 5900.
