I was thinking about buying one of the rotating assemblies off of ebay. From the mustang depot. I was looking at a 331 kit with all forged internals, has anybody used any of these kits before?
heard good or bad things?

The kit had low tension rings, which might be ok for racing applications (assuming the builder knows they are low tension), but for a street motor they create way too much blowby. I did a leak down test: it was 20%. I had no choice but to rebuild it.
Just make sure you specify the bore size, piston dish, ring package, and anything else you can think of. They did swap out the pistons in the kit for me, so that I could get the low compression I was after. No additional charge.
I am happy with the purchase. Just don't expect them to design the motor for you. Decide what you want before talking to them. This should be done with any aftermarket purchase though, regardless of the company.
