Six Pack question
It's been a few years since I had my Six Pack set up but I have to say it was the most impressive running system I have had. Back in the day I had a built 340 and ran everything from the stock Thermoquad, a 750 double pumper and then the Six Pack. My engine had custom head work to handle the larger cam and valve train, lifter, rockers. The six pack really made the engine come alive and would pull to 7300 RPM's.
The thing is I had to modify the outboard carbs to handle accerlator pumps, metering blocks and fuel bowls from 750 double pumpers. I also had to build my own progressive linkage because I made the outboard carbs completely mechanical just like on a double pumper. I ran a 4 speed and 3:91 gears, at highway speeds of about 65-70 it would get 14-16 mpg on extended rides. Around town without jumping on it would get about 10-12.
I did this work back in the 80's when my car was just another 10 year old used car, I had access to a crate full of old used Holley's that I could scavenge for part also.
