Swapping in a big block

I have ordered the Schumacher mounts this afternoon. I was just asking about the rear, I really didn't expect it to hang with 650 hp, but then this is my first (technically second) Mopar. I am used to building fast Buicks. As far as the brakes, I will likely be switching to a hydroboost since vacuum production is not likely with my cam. Power steering would be nice to keep. We shall see. I planned on subframe connectors from the get go. What do you guys suggest- off the shelf or build your own? I am loking at the Milodon hemi low pro pan, Schumacher said that one works. I have 10" Toyo slicks with Centerline Fuel drag wheels. I have been trying to decide what rear to go with, a fabbed 9" like Currie or a custom d60 like the Strange S60. This car is being built for a specific purpose- 10.5s or faster. I just wanted to pick some Mopar brains, I have a mechanical engineer helping with chassis set up, he has built tube chassis cars and several serious dragsters. It should be pretty fun!
