Default Tremec 3550

I have a '67 Mustang with a 410 hp / 438 lb torque. I've had an issue with the transmission locking up after "pushing" the RPM's over 4500-5000.
I'm told the T5 I have isn't strong enough to handle my motor.
Also told I need the Tremec 3550 because that WILL handle it..
your opinions please??

Yeah, that's probably pushing the limits of a stock T5. But there's guys that have taken stock T5s in the 10s. If your not aggressive with the shifting, they can hold quite a bit of power. You can also rebuild them with aftermarket internals that will easily handle your power. I don't know what's involved with the 3550 swap, but a good T5 rebuild is going to be cheaper. Just my opinion.
306 with all bolt ons, letter cam, ported E7's, T5 swap, full exhaust, 3:55's, 2" drop, and the worst paint you'll ever see or feel.

What about a T45? Will that be better than a 3550?

Its all about the budget like always. If you have the money buy something you will never have to worry about. If your budget is limited 88 makes a nice point.
