I had a 670 Street Avenger on my just removed 350. I tuned that carb. as close as I could to perfect. If I take it apart right now I think that it has primary jets one size down from what it came with and every other jet or setting is at the standard setting. The folks at Holley really do have them set very well right out of the box.

My 670 worked right out of the box. Minor adjustments, not jet changes.

I used the 770 in the 355 SBC, and it was very nice. Specially, the tuning of the secondaries' vacumme with the color-coded springs -2 screws and remove the cap!

I have never tuned a regular vac sec carb before, but I've heard that requires partial disassembly of the vac housing. :eek :cry
