I got myself a 4 bbl intake for my 364, and did Docs modifications. Is this considered a square bore pattern even though the holes are different sizes? Looks like 1 and 5/8th in front and 1 and 3/4 rear. Typical spread bore pattern is vastly different in size front to rear. Either way, what are my carbs of choice?
Yes. That is the square bore. The spread bore is very obvious. I would contact Matt or his dad at at Centerville Auto Repair about the carb. Edlebrock is a good carb but if you are running the Dynaflow, you may need help with the throttle linkage.
I've got a Edelbrock 750 on my '63 Riv. Here's the Dynaflow switch pitch linkage, I can get a better pic if needed:
Thank you for the confirmation of the square bore carburetor! I am actually getting rid of the dynaslow and torque tube. Got a ‘61 drop out center section and will be setting up a triangulated four bar. Already have a ‘66 ST400 with ST 300 converter. And carb linkage from a ‘66. Along with the switch to a 4bbl and dual exhaust, it should all really make it feel like a different car.
You'll need to use either an AFB style ( stock Buick or Edlebrock) or Holley carb with that, probably around 700 cfm.
I just bought two Edelbrock AVS2 carbs, a 650 for my sons 306 Ford and an Well, Im gonna try the Eddy AVS2 in an 800. I was told to use a 750, and 800 isnt much more. Thinking I could slightly limit the throttle so it doesnt open completely
