Runs super strong and I run a 3:73 gear with a 350-turbo trans 700r4
coming later. I run a 750 vac sedary holley but with the rear metering
block so I can jet the rear of the carb too. I run 72 front and 78 rear jets.
I run the RPM intake also but the torkerII will work as well. The RPM will
fit under the hood of the 67-firebird at least it did on my friends firebird.
Hope this helps and thanks to Gach for his info. I run 38-40 degree timing too.

Yes you could do that, but also even with cam change read what blueghoast did to his vacuum secondaries Holly crab. So this is kind of how it works. Evidently with cam your running now, it need more fuel on the secondaries going to a better cam and intake and not changing the crab like blueghoast did is going to compound the issue you’ll be disappointed. So definitely make the modifications to that vac secondary carburetor. Trust me thats a issue with those carb’s.
