Powerglide/ Turbo 350 swap

I have a 1967 Chevelle with a powerglide in it. I recently came across a Turbo 350 out of a 1967 El Camino and I was wondering how difficult it would be to swap my powerglide for the turbo 350. The car has a column shift and a 230 strait six. The engine is being beefed up and I wanted a better tranny. Would i have to replace a lot of parts, or would it be rather easy? Any information would be greatly appreaciated.

the powerglide can be rebuilt and will take anything the 230 - 6 cylinder will throw at it

It really isn't a matter of power, it's more about the fact that I have 2 forwar gears. This is not a combination that amounts to anything but slow. The gear ratio's are too high in first gear to accelerate at a fast rate. The top end is fine, but i want a lowwer ratio in first gear.

Hi sicksixseven,
The swap you mention should be fairly easy. Check the Turbo 350 and make sure it has the short tail shaft - 6". I helped a friend do such a swap some years back and it was a basic bolt in. If the 350 has the short tail shaft the drive shaft you have will work. The crossmember will work, you may have to elongate the mount holes an 1/8 to 1/4 inch. Use the converter etc. from the 350. The only thing I'm not sure of is your column shift linkage. His had an aftermarket floor shift. You will also have to find a bracket to hook up the detent cable to the carb. It should be fairly easy to do and you will get that lower first gear to help on take off.
Good Luck,
Mike

I have searched the internet and found that the general consensious is that you really can't use the stock column shifter, and that a floor shifter is the best choice. I have found a Hurst Indy Matic-1 Shifter on jegs.com, and i was wondering if i could use this when i swap the powerglide for the th350. Any information is greatly appreciated.

sicksixseven,
I don't see why the Indy-matic wouldn't work. Its a universal shifter and fits several different transmissions. There are a lot of shifters that would be better, but, if bucks are tight it should do the trick for now. You would probably want to replace it with something better down the road.

Cool

I would think shift linkage from a Chevelle with a t-400 or a later Chevelle with a t-350 would be easy to add to your 67 car if you wished to maintain the column shift

i don't really have any qualms about switching to a floor shift, but if the indy isnt a good shifter, than what is?

Hi,
Well its really hard to tell you what would be the best shifter to get. There are a lot of them out there. Both B&M and Hurst make some good shifters. The Indy is a detent style shifter and doesn't offer as much control as a ratchet style shifter. Also, it is not as sturdy and solid as some of the slightly higher priced units. Take a look at Summit Racing or Jegs web sites, see whats available and compare the features of each. I don't think you'd go wrong with any of them. Choose something that would look good in your car and fit your budget.
Regards,
Mike

Tranny swap

You might consider using a 200R4 overdrive automatic it's the same length as the 'glide.You will gain some miles per gallon highway and the lower gear will get you off the line quicker,best year to use: 85-87 Monte Carlo.Good Luck!

The stock column shifter will work just fine. I converted my 67 wagon from PG to TH350 and kept the original PRNDL setup. It keeps the stock neutral safety switch in play and also keeps the back-up lights functional.
