Swappin 3 speed for th350
 

Do I have to get a different driveline to take the 3 speed out of my truck and put a th350 in? Also what crossmember differences are there if any? Or anything else ive overlooked. Oh its a 67 lwb small window.:new:

You won't have to cut your drive shaft if it's a 350 turbo "short shaft". You will need an auto x-member, either an auto column w/linkage or auto floor shifter, and an auto trans radiator or cooler. You'll also most likely have to change your speedometer gear in the trans.

thanks for the info. Also do i have to move the motor forward to the front tower holes or leave in the back?:dum:

Re: Swappin 3 speed for th350
 

not if you already have a V8 in there now. I believe 6cyl engines were set back.

I did this on my 6cyl 70, I only had to have a trans cooler and a crossmember,

Driveshift stayed the same, no idea which tailshaft was on my 350, and get
this we, we modified the 3spd Indy floor shifter I had to work w/ the auto :crazy:

Would you need a new Auto flexplate, ringgear, starter?

Re: Swappin 3 speed for th350
 

I have the flexplate/flywheel, torque converter, and transcooler. I need the shifter so I dont have to change columbs, and a crossmember.I installed the v8 to replace the inline 6 but put the motor mounts in the same spot cause i couldnt move it forward with the 3 speed. So I think I need to move the motor forward, but do i need new mounts to do this?Any other info would be great thanks.

What happens with the clutch and brake pedals? Do you have to swap them out with an automatic pedal set? I am getting ready to swap out my 250 six and three speed on the column so I can learn from this. Thanks

I have just pulled out my 6cyl I will be putting a 327 in its place however I do not beleive you have to move the engine forward I may be wrong. I still havnt put mine in yet waiting on a flywheel I will be putting my gm 3 speed back in since its all I have right now.

So after all this I am now thinking I want to stay with a stick shift soo does anyone know of a good 4 or 5 speed trans that will bolt in with minor mods?
