Thanks for the input everyone.
I thought 3-1's would function better than other setups on these straight 6's, if properly sized. Since the intake runners are in pairs each carb would feed 2 cylinders. And the rest of the intake would basicly funtion as balance tubes. But it appears it will hit the firewall and I don't want to modify the firewall. I could fab my own, I work as a machinst at my day job and have all the tools, but I'm not sure how the unequal runner length would effect the tuning of the engine. Any thoughts?
chevman32, thats very cool! What car was the engine in? Do you have any pics? My aunt and uncle live in Santa Ana, I was just out there in April.
