What crate engines is everyone using??

I don't buy crates, or recommend them unless it's from a reputable builder - meaning a machinist that will custom build you one and it arrives ina crate. Not it's a cheap price from a large "crate engine" emporium with a few custom touches for you in it. As was posted in another thread: Fast, Cheap, Reliable - pick your two.

As far as Indy goes - Run Forrest! Run far far away. The last Indy crate I had my hands in was a 432" B wedge that was $10K 10 years ago, was marketed as a 500hp package, and managed just shy of 425 because of terrible head work & poor ring sealing (it was supposedly dyno'd at Indy). It also smoked a little and had leak issues.

My $.02 - If you want their parts, use a reputable dealer and have a reputable shop make use of them. Do not go direct to Indy.
