Well,, Im going with an automatic,, and my 64 came with the popular Power glide--- and Im considering up-grading to a 350, or 400 or 2004r or even a 700r4 ...

I've decided to "not" build up my car into a massive hp car,, its going to be a cruiser,, I will build the next one into a mustang killer.

Its going to have a mild 327,, and I was wondering even just for crusing is it worth it to go all the way to a 4 speed auto. Or would it be cool with a 3 speed ? I know the 200-4r can just fit right in without shortening the drive shaft.
Im also considering keeping the power glide. Does anyone know the gear ratios for the PG - 350 & 2004r ?

Im also concerned about the shift linkage for up-grading,, its a colum shift,, and im wondering if the other trans. can hook up into my linkage ? ?

Any advice ?? much appreciated .

Depends on what your going to do with the car overall, and what the rear gear ratio is or will be.

If you plan on any long distance cruising then the 200r4 is the ticket or if you plan to run a 3.55 or deeper gear (I would put in an OD trans on any gear deeper than 3.08).

If you are only going for a Saturday Night cruiser then the TH350 with gears taller than 3.31s. TH400 is a great trans if you need the durability with a cruiser car and a 327 it just is not needed. Leave the PG for the quarter mile campaigner (I never liked a PG for the drags either).

Trans gear ratios

PG for a 6 cylinder 1st 1.82 2nd 1.00
PG for a 8 cylinder 1st 1.76 2nd 1.00
TH350 1st 2.52 2nd 1.52 3rd 1.00
TH400 1st 2.48 2nd 1.48 3rd 1.00
200 4R 1st 2.74 2nd 1.568 3rd 1.00 4th .647
700 R4 1st 3.08 2nd 1.625 3rd 1.00 4th .70

I just finished installing the 200 4R in a 67 300, 283, AC car. It has 3.36 gear from the factory. The 200 works great. The column shifter is not too bad to work out. You can set it up something like the turbo 400 in a chevelle.

I would run a 200 4R with 4.10s.
The 200 4 R is a bolt in replacement for the Powerglide and Turbo 350. You will not have to shorten your driveshaft. Bowtie Overdrives manufactures a Transmission Crossmember that uses the existing holes in the frame. This crossmember also allows you to remove the pan for a fluid and filter change without having to remove the crossmember.

Contact Shiftworks to modify your shifter:

Also, please check out Richmond's Street performance Calculator:

http://www.richmondgear.com/101032.html

For a 200 4R, .67 is the Overdrive.

Just to illustrate, at 70 MPH with 3.08s, a Non Overdrive Transmission and 25.6" Tall tires, your 327 will be turning at 2830 RPMs.

In comparison, at 70 MPH with a 200 4R, 4.10s and 25.6" Tires, tour 327 will be turning at 2524 RPMs.

I don't like the 700 R4 because you will have to hammer out the transmission tunnel and shorten the driveshaft.

Also, the 200 4R has a numerically lower (higher) first gear for a better launch. If you take into consideration the Overdrive of the 700 R4 at .70, the RPMs at 70 MPH with all of the same information listed above, jumps to 2637 RPMs.

In my opinion, you will have the best of both worlds with the 200 4R.

Agreed. The 200R4 is a much nicer overdrive than the 700R4. The 700R4 first gear is too low and too far away from second gear. This makes for a bad lurch on the 1-2 shift. That would be a bit crude for your Chevelle. The 200R4 has much better ratios for the 1-2 shift.

Wow !! That pretty much covers all bases !! you guys are awesome,this is going to save me alot of time !! , does the 2004r need the switch for the over-drive like the 700r4.. i know they sell a kit for it on the 700 - but is it the same with the 200 ??

Painless sells a wiring kit for the lockup and you need to purchase the TV Cable. All items should be available from Bowtie Overdrives.
