Well after talking to two more very reputable shops about building me a TH350, I decided on the TH400. I am doing some wheelin and dealing with my bro in law . He has a fully rebuilt one with an upgraded sprag and transpack in it. Getting it for about 200 bucks so I cant go wrong. All of the shops felt that with 3400 lbs and a 408 the 400 was the way to go. Especialy if I plan to run slicks and get the sucker to dead hook at the track. So as it stands it looks like TH400 with 3.42's!

With the weight, power applied and rear gear, I suggest you read what I suggested here =

Good luck,
