So are you in Austin with it now? That's going to be a killer, up in Junction City knowing that it's down in Austin calling to you....
The car is in Austin and I am in Juction city.
I am looking to change the transmission or the gears out. The axle is a ford 9in so the gears are easy to change. The transmission is brand new but not going into second. So need to do some research on the powerglide.
Things I plan to do now.
Check timing on motor
Cant decide if I should rebuild carbs. Starts easy with no leaks.
Figure transmission 2nd gear out
Install Brake Booster
New interior
Clean brakes up (surface rust from sitting in storage)
I would re-think the OD trans. If the R's come down too far, with the cam that's in there, the motor is likely to load up, foul plugs and begin coughin' back through the blower. That's where things are gonna get REAL EXPENSIVE, REAL QUICK. I don't know for sure, never had a blown BBC with a radical cam, but I'm bettin' that the best plan would be to leave the 'Glide in there and maybe even consider more rear gear. The only reason you might want an OD trans would be for fuel mileage and you darned sure won't get any fuel mileage with that combination, regardless of gears. If you want fuel mileage, swap in a stock 305. COMBINATION, COMBINATION, COMBINATION. Seriously, before you screw the pooch, talk with some other fellows who have this combination on the street and get their recommendations. Sounds to me like you're trying to turn a race horse into a plow horse.
"Figure transmission 2nd gear out"
The builder may have modified the valve body to a manual shift mode only, by blocking the shift valve open. If that was done, then there will be manual shifting only and whatever gear you left it in when you stopped, is the gear you start out in when you leave again. Manual shift means manual shift, up and down. Look and see if there is a vacuum line from between the blower and the carbs, to the transmission. I'm bettin' there ain't one. I don't see one in the pics.
"Install Brake Booster"
I wouldn't expect this to work out real well and would suggest an electric vacuum pump to work the booster can....too much cam, very little vacuum....

Or a complete Hydraboost system if there is a power steering system on the car.

Unfortunately I think Tech's giving you a lot of good advice. With the blower and big cam the Camaro is not intended to be a highway cruiser, so the PowerGlide is really not a bad choice - they were used in a lot of strip cars back in the day, and they're a very strong tranny. If you find you want/need another gear then maybe jump to a built TH350?
Tech's right on for the brake booster, too. A traditional vacuum boost unit is not going to get enough vacuum, especially at idle, and you could very well end up with zero boost when you expect it to be there.
On the surface rust on the brakes, I'd save my money and see how they look after a few stops once you're driving it. It's totally normal for rotors to surface rust during periods of down time, just from humidity, but they clean off the first time you use the brakes.
Exactly, or a TH400.Quote:

I have decided to stick with the powerglide. But the original plan was to change the rear gears out to a higher gear and install 700r4. Not looking for mileage as much as looking for drivability around town. Just looking to take the car into town for dinner and maybe a movie.Quote:

There is a location on the power glide for a vacuum but nothing is hooked up in this location. I have not had much time to play with the car to inspect the transmission. But I do know first and reverse work.Quote:

The Hydraboost system is a good option. It does create extra power steering lines within the engine compartment. If you have ever run this system did you notice any lag in the steering after the extra fluid is added? Also this would eliminate the electric vacuum pump.
OR, think about the combination and use an OD trans where you control the OD! Say.. for highway use only..??..??
or, like a Final Gear selection can be as small going from the 4.11 to a 3.90 and watch the tire sizes as they can be a factor too!
Yep, all about the combination but don't rule out anything without thinking it through!
