F 85 Rocket Car part3

The numbers weren't to bad on the dyno but we knew we had to change the intake manifold, distributor and wires and carb. Off came the edlbrock Q4B, which didn't flow unless you were over4500 rpm. ( not good for an Oldsmobile ) and a stock cast iron intake took it's spot. A brand new edlbrock preformer carb and a MSD 6A box with distributor were installed.
The next step with the drivetrain was the trans. The turbo 400 needed some freshening up, for that it was taken to Rodgers Automotive in Chantily Va. They did an excellent job putting there touches on it. The one thing I was afraid of was getting to much stall in the converter. I went with a 22-2400 stall, but as it turned out, not nearly enough. I had to powerbrake the car in drive, it would not idle unless you had the idle turned up so high so you were killing u-joints when going between drive and reverse and park!
The car had a 3:23  posi, so because of the drivability of the car, I found a 3:91 posi. With that rear, this car will launch!
Our original plan was to build the car so we could race the 1/8 mile, which as it turned out worked quite well. My sons and I will take the car to the track and the rule is , whoever quailifies the car the fastest, gets to run the car that night. Well, my oldest of course always does the burnout from hell ( mainly because he's not     paying for the tires! ) so he get a quicker time. Our times were respectable, but the end of the first season we had tweaked the times down a little.
In this off season we have done some work that we haven't tested to see if there is any positive results. I installed a 3000 stall converter. The drivabililty is much better. 90/10 shocks on the front and adjusted the carb. ( Which actually I have an original quadrajet on now. )
So, stay tuned for the first visit to the track!
