It completely depends upon the condition of the transmission.

Write it as I read it.... If it was good enough to go behind a 426 in stock form... well that good for me at its stock limit.... Just saying.... 450 HP should be good in my book... "As a Hunch"
Now how well off a use hunk of garbage someone puts together, well thats another story.

yep, agreed. the 727 can eeeasily handle that kind of horse but that power is also gonna find anything wrong with the tranny in a hurry.
