I'm thinking of going with a 700R4 behind my bigblock. Now I have next to no experience with GM stuff and the same experience with auto's. I was looking at bowtie OD as they have had a few good words said about them in threads, but I have also found a few bad ones too. I expect that happens for any business. I just wanted to ask about other builders that can build a 700R4 to take 350-400HP and 500ft lb torque. Car is street driven, not bashed on ( thats what my roadster for) and will do duty as a family holiday cruiser. cars about 4000lbs so heavy enough. As for 200R4 , I have read people saying gear ratio wise they are better between 1-2 but their not a trans thats known in Australia, where the 700R4 is, as we got them on local GM stuff, so would prefer to stick with that for longevity and if there are any issues down the track. I spoke to Bowtie yesterday and basically 2k delivered to my shipper for a stage 3 trans and all the other bits needed to put it in the car. Now its not cheap, and really what i'm chasing is getting what I paid for, I'm happy to spend the money, I just want to make sure I'm getting the trans from the right shop. So anyone used bowtie to build a trans for their BB and how is it? Any other shop recommedations to speak to? I have looked on the Auction site, theres a few there, but how the hell do you know?!? cheers.
