I don't know much about non GM transmission but I do know about the 700. The 700 R4 can be built solid to handle that 454. 1rst gear in a 700 is lower than both the 350 and 400. Make sure that you find a 30 spline not the 28 spline 700 used in most 6 cyl. models. Look for a late 80's early 90's. If you have a Dayco transmission parts shop near buy get the ceramic disk upgrade with master overhaul kit and have a recommended bench tech install it. You will also need to buy the 4th gear electric lock up conversion getI think summit has it? The stock disk packs in the 700 and a lot of other stock transmissions use a minimal amount of disks for each gear+ the stock disks are coated with a paper/cork material- This is what fails in these transmissions and this is why the 700 gets a bad wrap. When you upgrade to the ceramic disks you get a better grip - and more disks working together for each gear.. You can build a stock 700R4 to handle 1000+ HP.
That's a monster truck what will you be towing?
