Will Posted November 28, 2012 Share Posted November 28, 2012 Hey Guys, getting on a bird home tonight and go the go ahead to go shopping from the wife. I'm thinking the B&M street strip trans should do nicely. Opinions? TH400 sitting behind a 468 putting out about 550hp. Also moving shifter the the floor. Thinking B&M as well, Drive when Im cruising and ratchet 1,2, and Drive when I wanna go fast. Thoughts or experience? Thanks Will Quote Link to comment Share on other sites More sharing options...
72 LS5 Posted November 28, 2012 Share Posted November 28, 2012 Do you have a 400 core already? Have you considered a local hi-po guy to do the build? Just thinking of warranty issues, shipping, etc. I would stick with the 400 - mine's still going strong after 18 years of "spirited" driving. It was built locally by a sponsor of the drag strip.

Sam (Bones) Posted November 28, 2012 Share Posted November 28, 2012 I feel there are much better choices out there other than B&M, been beating on my 400 for 15 years and was pushed to the upper 10'second range and it was done by a local reputable shop Quote Link to comment Share on other sites More sharing options...
71monteme Posted November 29, 2012 Share Posted November 29, 2012 go to your local drag strip, find out who they use and have one built for you. nothing beats a face to face relationship, plus it support your local business. most of the time it is cheaper too. all of our trannies from street car to our 6 second sportsman car comes from the same guy. thanh Quote Link to comment Share on other sites More sharing options...
502ci Posted November 29, 2012 Share Posted November 29, 2012 Had my 400 built by a local transmission shop (Cottman). Been beating on it for 8 years now with no issues. I knew I was at the right place when I walked in the shop, they had a wall of photos of customers classic cars that they had worked on.

zmanabba Posted November 29, 2012 Share Posted November 29, 2012 I agree with all of the above. As far as a shifter I have a B&M Quicksilver I have used since 1984 still works flawlessly and I still love playing with it. David Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted November 29, 2012 Share Posted November 29, 2012 If you have a 400 I would agree and have it rebuilt. I have a Rossler TH400 but it is a little different from stock rebuild. Quote Link to comment Share on other sites More sharing options...
Will Posted November 30, 2012 Author Share Posted November 30, 2012 Thanks for the info guys, Im def staying with the 400 no matter what. Just a matter of what brand. Ill do some more local research though. See if I can find something better at a local speed shop. Quote Link to comment Share on other sites More sharing options...
Dans '70 Z20 Posted November 30, 2012 Share Posted November 30, 2012 You can also try speaking to local racing engine builders. Everyone knows the respected guys in their area that the race guys prefer. They likely work hand in hand on many race cars and can recommend a reputable performance tranny shop for your build. One word of advice. Build the internals of the tranny to what your eventual goal is with the motor ..... not to simply what you have today (Other than the converter which is matched to current cam specs). Always better to over build if thats the direction your going rather than blowing it up when you get there and paying twice to build tranny. If it is built right the first time a built Turbo 400 (as stated above) will take a lot of abuse before it retires. Dan Quote Link to comment Share on other sites More sharing options...
Will Posted December 7, 2012 Author Share Posted December 7, 2012 Ive got a working th400 core. I got hooked up with info of a local race trans builder. hopefully gonna talk to him today about doing a beefed up rebuild. Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted December 15, 2012 Share Posted December 15, 2012 Def hold off on the BnM thing. I lost my second trans on my 81 Bu last week after 6 drag strip passes. I generally build my own but this was originally a customer leave behind. Let's see what they do through Summit. Quote Link to comment Share on other sites More sharing options...
Will Posted December 15, 2012 Author Share Posted December 15, 2012 Yeah, I took everyones advice and found a guy who guilds local race trannys. Going with a beefed up TH400 that can hold 800hp, forward pattern manual valve body, and custom continental torque converter. Spending more then I planned but the extra strength should be worth it. Looks like I just may not get as much done on the interior as I hoped. haha Quote Link to comment Share on other sites More sharing options...
