Hey guys,
It's about that time to get a tranny for my 67' Fastback. My car's got 408w stroker, victor jr. ported heads and intake, forged internals with 10:1 compression. Probably putting 525-550 BHP, plus I plan on running a 100-150 shot of Nitrous. I was looking to get the T-56 (1386-000-012
) which is good up to 450hp/610ft/lbs trq. Do you think this will handle this much power without running slicks? Or would I need to go with the TKO or TKO II?

Ask questions if you have'em, anyone who thinks they're too cool, know's it all, or doesn't want to look stupid has more problems than you.

i'd say get the TKO. the T56 won't hold up to your power without an expensive strengthing. i have had a TKO in both my coupe and droptop and i've been very happy. imho the TKO is the best way. ![[patriot]](graemlins/patriot.gif)

If I'm not mistaken the Viper-spec T-56 is stronger than the TKO (doesn't Treynor's 850 rwhp Viper use one?)

if it does, i don't think it's box-stock. he has probably gone through it and built up the internals for 850+ .

If you get the Viper-spec tranny and shift like a normal human, you shouldn't have a problem. It's when you start abusing it that the tranny breaks. I'm sure it's something Dodge and Tremec engineers looked at before deciding to put a T-56 behind the new triple 500 V-10.

You're not running sicks so the regular TKO will be fine. Shoot, even a 3550 can last for ages if you don't drive it much and don't use sticky tires.

Im running basically this exact same setup. I have just a few less cubes, a tad more compression, same heads and intake, and a demon. Even with what I considered my cam to be...HUGE, I honestly didnt think Id be making that much power. Thats definitely enlightening.
Im running a toploader and a centerforce clutch.
