I had similiar dollar figure to spend and went with a backdraft from anthem motors. 392 crate engine, 4 wheel disks, IRS, covers your requirements...backdraft is worth a look. I have pics of mine in my gallery. My total cost was 40,315 but I could have saved 1200.00 if I didnt get the
oil cooler and ceramic exhaust. Good luck, the research is half the fun. Lots of good mfg's out there but the backdraft seemed to be best suited for me.
