Re: BBC Transmission ?
If you are going to beat on it a turbo 400 if its just a cruizer I go for the 700r4

Re: BBC Transmission ?
Turbo 400 if you want auto with strength, 700r4 for cruising and fuel milage, and if you want to flat out tear stuff up, you gotta go 4 speed

Re: BBC Transmission ?
For work truck turbo 400. driver not beat on 700r4. I have had extremly good luck with turbo 350 in my race cars. Yes I upgrade them but I've run them behind every kind of engine from stock 283 to 468 BB. The one in the 72 nova now has 2 seasons running and still works. I am going to freshen it before I take it back If I get to race this year. (health issues) I have had 350 turbos in old trucks that I have towed with and worked hard without any trouble. I guess what it comes down to is what you want to do with it and how much money do you want to spend to get it done

Re: BBC Transmission ?
Running a TH-350 behind my BB. Had it rebuilt and beefed up a bit. My understanding is that it takes about 25 more HP to spin the TH-400. I tend to drive pretty easy so I don't anticipate any problems at all. Good luck.

Re: BBC Transmission ?
Not a 454... but I have a Th350 backing up my Caddy 500. Only been driven 6 or so months like this, but it is holding up quite well, and we can pretty much call it a junk yard unit.

Re: BBC Transmission ?
I have three or four so lets look at he Blazer first, 454/4-speed(truck)205, then the 67 has a built turbo 350, the 90 454SS has a built 700r4 and yes I beat on it regularly and I also spent nearly $2k on it. I had a 454 in my 70 Camaro w4-speed (muncie) and I am here to tell you banging gears is the only way to go. TKO 5-speed is on the way for the Camaro and possibly one of the trucks (2wd)

Re: BBC Transmission ?
I would run a TH400, or if you got the bucks, use a 4L80E. They are stour enough to back the BBC up.
