Building a TH400.. What's needed? Motor made 610/620 crank, and down the line may be sprayed with a 150 shot. Now onto the tranny.. Currently it is a "stock" TH400 with a 2500 converter in it. What parts should be upgraded? I've been told I need to put in a stronger sprag, a bigger convertor would gain a lot, and that it'd be awesome to add a T-Brake and RMVB Any input? And if you know, how much are these things and would I be able to install them never seeing the inside of an automatic transmission before. Thanks fellas, you guys always have good input. |
Hit up Greg at FTI. I love my TH400 and converter he built for me. |

One more question. Trans currently has a Holeshot converter.. about 1/4 the price of a good one.. How do I know if it's slipping too much or how much it's holding me back? |
All the stock hard parts should be good for that power. Just takes the right build. |
Camaro, give me a shout at 1-866-726-8358 and we will go over everything that you would need according to your plans with the car and i will give you a quote. thanks, Greg |
