still kickin the idea of puting 383 in the 63 dart. questions:
how much would tunnel need to be changed to put the long tailshaft 4 speed in?
None.
will there be room for Z bar and exhaust to go stock location with big block exhaust manifolds?
The Z bar may need to be modified. It's only a tube with two arms stickin off. Not rocket science. lol
can SB tranny be adapted to use on big block bell?
Automatic? Yes, with an adapter plate. Manual? Just swap bellhousings.
any interchangability between 63-6 A body 4 speed pedal assm amd 63-6 B body??
Yeah, the B body trans will bolt in. The shifter location is in the wrong location.
do the early big block trunion trannys show up at the big swaps? and cheap like used to be years ago???
Transmissions are the same big to small block except for the 18 spline VS 23 spline input shaft. The ball and trunion transmissions are actually arguably stronger then the slip yoke transmissions. I would look for an early ball and trunion A body 4 speed. You already have a ball and trunion drive shaft. All you'd have to do is make it the right length. People will argue the ball and trunion setup is weak. Can you say Max Wedge?
yes i know, put the slant in the 63 Dart and get early B body for the BB and 4 speed!! LOL
