Ok, I had a chance to pick up a complete 400sbc for cheap that needs a rebuild. My only concern is weather my rebuild 700 w/ 1900 stall will be able to handle the torque? Could I get by with it if I get a big trans cooler and shift kit? Or is it just too much for that trans to handle? I don't have a heavy foot when it comes to this truck, I have a Buick GN for that, so I won't be beating it to death. Just want that torque for the trails. Maybe I should just ditch the 700 and get the TH400 that these engines came with? I'm on a tight budget so I don't want to spend all that much on this swap if I can.
