It comes down to how you drive, not just how much power you have. You could have 600hp and make a stock tranny last, or have 250 and grenade a built tranny. For a decent amount of drag racing, your example is probably starting to push your luck if you're going for good 60' times. IMO torque and how you launch are the two main transmission breakers, not hp so much.



Oh, for the actual question: A stock tranny vs built would have some impact. It wouldn't make or break the sale itself, but I'd probably be willing to pay a bit extra with a built up transmission; no where near what a built tranny would cost though.
