I can finally beat up on my 347 with out fearing the fury of t5 gods. I installed my 3550 this week. Nice and stout transmission. I like it.
The t5 was the 13-52-199 rated for 300 Ft # of tq. It was not beat on either. Shifted perfect no grinds no vibes no problems.....
So you gonna tell me that you dont beat on your 347... Go buy a civic I had the WC T-5 behind my 347 and it didnt last 1 summer....
I didnt beat on it with the t5 because I know how eaisly they break. I broke the t5 in my 66 resto mod. So I babied this one untill I could get the tremec. Now its getting a beating. it looks like thiss when I beat it =================== ============================= =====
That is what its rated for but I have seen and personally know some people running 500-600 ft/lbs through them with no problems at all. You'll love it.
