HiCustomer my name isXXXXX and I can help you with this.
I've been waiting for a question like this ever since I joined Just Answer.
My ads use to read, "Fix all Column and Ignition"...
Nickolas you either have a Saginaw Tilt or a very similar Non-Tilt.
Which is it?
Either way, your floor shifter is/was hooked to your column using a cable that worked a lock rod that runs along the left top of the column or it operated thru the action of twisting the lower collar on your column when you shifted the gear. This rotated the lower bowl, locking or unlocking the ignition shift rod.
I can give you blow by blow but you won't need it if your replacement column is in good shape internally.
Your new column (used) will work fine for you as long as you can bolt it up to the fire wall and still connect it to the dash hangers under the instrument cluster.
As far as removing the shift handle on the replacement column goes, just drive the pin out and pull the handle off. It will only operate the shifter if it is connected at the transmission shift rod near where it passes thru the firewall.
About your 309.
I never had any luck making my old 307 put out lots of power, I had more luck with old flat head Fords.
Because most of the speed shops today focus on Japanese import I don't even know where to send you for answers you need.
Hotting up an old GM v8 isn't a popular hobby anymore.
If you are planning on keeping your car, do yourself a favor and get yourself a Steadfast Security Collar for your steering column.
This will make it very hard for anyone to steal or tear up your column to steal your car.
They use to cost me $119.95 and they are fairly easy to install, just make sure the inside of your replacement column is in good shape because removing one is harder than putting one on is.
Also, it is very easy to install a Kill Switch, just hook up a toggle switch between the ignition wires going to your switch and put it someplace where a thief isn't likely to look. Like in the fold of the seat or next to the transmission hump next to the drivers seat, or under the seat. Never put one under the dash, they look there first.
Unless you replace your steering column with the same type that was damaged, it will be impossible to shift on the column and lock the transmission with the key.
Sorry, the designs don't match.
I hope all this helped you figure things out. If you found this info helpful accept my answer, if I didn't help you enough, ask for clarification.
If you have any further questions or need clarification, just ask.
