It does depend on how you will be driving it. The t-5 will take a moderate amount of hard usage. I have heard that a person can wreck one in minutes easily. I don't actually know anyone who has done that. I do know of people with t-5s behind built 350s who have had no problems with them. I have one behind my stock rebuilt 350 and drive it hard at times with no problems. I do keep a spare in the shed "just in case" though.
