Install a Tremec T56 Magnum in your A-body

I don't really care. I was just offering known advise. It's a good setup used within its limits. I was highly advised by several NOT to use this transmission behind my LS3 because of the power it makes. More than or as much as some 440s. I have a smallblock cuda's the only reason I'm here,,, and maybe a decent deal on parts now and then. If you hammer it behind a good 440 or a lot of power, you will break it. Also replaced several hydraulic clutch setups over the years. Not good for long term,unless your ride sets in a garage. But whatever, I'm just tryin to help. Just remember if yo take my advice on power you'll be fine. If not I'll never know, but that little voice in your head will keep sayin, he told you so...
You are wrong.
