bald eagle. forget the elec fan, look stupid and just another thing to go wrong, like I said the 235 is definately shorter, if you use the late 235, look on ebay or I will send you the link . theres a guy that has a adapter for yse on a late engine that will yse the early 235 pump and even shortens the motor more, as for the treans, I used a buick trans on a sb chev a few years ago, I'm not sure on the torque tube but the trabs will go onto the truck bell, the trans is very strong, you will never break it, the problem is that alot of guys just go with the new stuff, it's easier, I am a diehard, I am not interesred in the end result ynless it looks like it came from 1955, hope this helps. by the way the jimmy is longer and if you want the cubes use a 261 chev, same dimensions as a 235
