I agree with Brent on the T5. I broke a couple of them behind my 285 HP 5.0 litre with a B cam and GT40P heads. After the last one broke, I ponied up (no pun intended) and bought a Tremec 3550. Never had another failure after that. I even swapped it into a 98 GT with the stock 4.6 and still no issues. I wish I kept it when I sold the car, but such is life.

I used to be a distributor for G-Force and Astro Performance T5 transmissions.  They are about as beefed up as you can get, with different gearsets, shaft supports, etc, etc.  Tony Sarvis used to tell me that even then, they wouldn't last long behind big block torque.  The case is weak and they just can't fit the size gears in them that they can with the larger transmissions.

Agreed, the T5 is a decent transmission behind a mild small block, but a big block in a heavy truck sounds like a recipe for shrapnel. I ran a stock T5 for years in my low 13-high 12 second 302 Fairmont, but at 3200 pounds, thats at least 700 pounds like than a 69 F100, and a lot less torque. When I started racing my 85 5.0 Mustang in Stocker Eliminator, I thought the T5 would be adequate, as the Mustang was about 150 pounds lighter, and the Stocker engine only made about 285 HP, but within a year, I had twisted the spline on the mainshaft so badly, that I had to use a hammer to bang the slip yoke to remove the driveshaft, cracked the main case, and knocked several teeth off 3rd gear. After that first year, I had 3 broken T5s to show for my efforts.

I've warned my dad about the T-5, but he has already converted it. His solution is to get a good scatter shield. I look at it like an LT1/LS1 with the stock 10 bolt rear. You drive it for years as long as you're easy on it. Haha, I'm sure everyone is correct about the T-5. If it ever makes it to Atlanta Dragway (before they close it RIP) I'll consider it a successful build. -- That's a different thread though.

Thanks for all the messages and help guys. I bought a Performer RPM from Roger (WerbyFord). I appreciate the knowledge and experience shared. Now I have to get back to the shop and debate carburetors.
