Six pack response...
I don't know how relevant this may be to your question, but years back Chrysler Power magazine there was an article on tuning six pack secondaries by changing the vacuum bleed size on the secondary vacuum actuators to control the opening rates. The factory carb bleed orifice size differed according to the application, this article showed drilling and tapping the orifices for socket head machine set screws and drilling the set screws for custom orifice size. The general idea was to open the secondaries as quickly as possible without making the engine bog under load.
Yes, thanks about that, I'm aware of the spring changes in the secondaries as well changing jets, even making the end carbs open manually instead of waiting for the vacuum to kick in. What I want to know is on a stock set up, more or less, how does it react. Is there that small hesitation ? When kicked at around 3k rpms do you feel the difference or does it just load and go as if it's any other carb set up at full throttle.
Now the reason I ask is I used to have a 440 6bbl car that was an original factory car and I'm not sure if it's the norm that it felt line it did, torque, B.B. etc. Compared to this small block I have now that doesn't have that torque that the 6 pack feels like a regular high performance 4 bbl carb .
I recall the original 6 pack, was " " heard, when it opened up. I can't say the same with the small block.
At times I feel like I may just go back to a 4 bbl set up and be done with the constant tuning of these 6 packs.
Dean thing does look nice, the jewel of any engine I've ever seen... Minus the elephant, but sometimes looks are not everything... I know, I see myself everyday when shaving and think, what does the missus see in me.Lol
Ok thank you.
