It should be a R150, one of the strongest trannies Toyota has put in a truck. I read somewhere on here that the clutch is good to 1600 ft-lbs. I would call Marlin Crawler - he would know.

thanks some more advice would be nice to................i only ask because some other guy has S/C on his 3.4L with the 5 speed but says he has blown the transmission a few times so im worried

I've had minor , non-blown, trans trouble (R150) , stuff thats rebuildable(synchros) . My trans has got 250k on it. The strain of 35's , 4:10's, V6 with exhaust and a couple other tweaks for hp, TOOK it's toll. So whould that ridiculous amount of blood-curdling power, I suspect.

apparently the R series tranny's are more robust than what's in the Tacomas (going off what's on Marlin's site - they just came out with a bellhousing to run the older trannys behind the newer motors just for that reason)

Just to give a view on how Toyota saw it:
The 7MGE cranked out about 180hp from the factory, and they decided to mate it to a W-series tranny, and they hold up pretty well.
The 7MGTE put out about 250 from the factory, and was mated to an R154(same guts, just different ratios). You arn't the first guy to soup up a 7M to 400+hp, and most are still running stock trannies.
Where you will have a problem is at your axles. 450hp will break stock Toy axles pretty easy, especially with big tires.
