Tranny swap ?'s
currently have a h400 in my 1970 c10, mild 350 (cam intake carb headers exhaust) and I've been looking at a new TKS i believe is the brand name, th700 R4. will this bolt right up to my motor? anything challenging to expect as i plan on doing this myself. also thinking of doing a 2000-2400 rmp torque converter at the same time

Re: Tranny swap ?'s
A TH700R4 will bolt directly to your SBC. I think the rear tranny mount will be the same too.
I'd think about 500 bucks for the TH400, if it's still in great condition. Gary

Re: Tranny swap ?'s
You will have to change the driveshaft yokes as they are different between the 400 and 700R4. If you had a TH350 you would be fine or 3OTT, but would have to shorten the driveshaft depending on the tail length on the 350. You may have to shorten the shaft anyway. You also will need the metric TC bolts for the TC, buy them at a parts store. You will need an adapter for the TV Cable angle depending on what carb you have. 700R4's hate heat so I would add an additional cooler to the trans lines. How are you going to lock up the TC or are you? Speedo cable is another issue to tackle and you may have some issues depending on what rear gear you are going to run. I have done this so if you want exactly what I did I, please PM me and I will send you every part number I did for my swap. I run 3.42's with my 700's and everything works like GM designed it to do.
Let me know Smitty
