46 chevy truck

I did a re-work on my 46 Chevy truck back in 2006. After driving it for a few years, I am ready to do some upgrades. It has been a long time since I have been on this site, so those that don't know me would never know that my first truck was a 1941. My first truck was a basket case. It was repowerd with a 327, turbo 400, open driveline rear end.

Now that I have driven my truck with the 216, I am going to build the truck I had 30 years ago. I have a 327 SBC, turbo 400, Mustang II front end and an S-10 rear with 3:73's on the garage floor. When the truck comes out of storage, these parts will all be installed.

Since I have been out of the loop, I am looking for the following input;

Steering Column....S-10 pre-airbag? What steering column fits in our 46 trucks nicely...besides the $700 customs?

Transmission...I have a Turbo 400 bolted to the 327, but after a long winter, I am thinking of upgrading to a 700R4 for the OD. If I use the 3:73 rearend, I am guessing my RPM at Freeway speeds will be up there. My mechanic friend tells me a 327 loves to run at higher RPMs and will be just fine.

Other than that, I should be starting work on this upgrade in April when the truck comes out of winter storage.

Engine, tranny and rearend prep will all be done by that time!

Input on a steering column and trans appreciated.
